Delivery

Shipping and returns

Shipping

Please be advised that delivery dates are estimates provided to Swiftronics from the couriers we have partnered with. Deliveries to rural locations may experience delays by up to 2 business days which is beyond our control. It is the buyers responsibility to be informed if their location falls under rural.

Shipping times may vary depending on the shipping destination and the shipping method selected. Please note that for any reason due to circumstances beyond our control shipping may be delayed (inclement weather, lost or stolen packages etc.)

Delivery of your order is subject to the availability of inventory from our Distribution Centre. Orders placed for in-stock products will typically be processed and shipped within one business day from our distribution centre and are included in the transit times.

Orders are processed and shipped Monday through Friday. We do not process or ship orders on Saturdays, Sundays or Holidays.

Pre-ordered products will be shipped within one business day of the expected ship date on the product page. Some orders may be delayed without notice due to shipping or production issues from the product manufacturer, in which case the order will be processed and shipped upon product availability. If a product is delayed beyond the expected ship date or is cancelled by the manufacturer, you will be notified via email or telephone and the order will be cancelled.

We may divide your order into multi-shipments depending on the availability of the products at the time of processing. In these instances, you will only be charged once for shipping.

Returns

  1. Not only do we offer reasonable prices and service, but we stand behind fair and ethical practices. If after receiving your item and you decide not to keep it, we ask that returns be made within 30 days of the item's receipt. Return shipping will be covered by the buyer.
  2. Items that have been used or show signs of usage, will be subject to a restocking fee no less than 20% of the original selling price will be applied to the current sales price. Swiftronics reserves the right to inspect any item before approving a refund.
  3. Requests for order cancellations made prior to shipping will be refunded minus 3% for transaction fees associated with the order.
  4. We offer a 30 day domestic warranty on all of our international devices which will be issued as a repair or a replacement if a repair is not feasible. This warranty applies to product defects and failures only. All warranty claims placed 30 days after the date of receipt will be redirected to the product manufacturer and will be subject to manufacturer’s discretion and return policies. Under no circumstances will liquid or physical damage be covered by warranty.
  5. All accessories, home theatre items, wearables and open box devices are final sale.
  6. In the event of receiving an item that is defective on arrival (DOA) please contact us right away so we can replace the item.

FAQs

Do I have to pay for return shipping if I want to exchange a product?

In the event of the buyer purchasing an item and deciding not to keep it for any reason other than manufacturer defect, return shipping will be paid by the buyer.

Received a defective item?

Contact us right away. We'll send you a prepaid return label and facilitate a fast exchange at no extra cost to you.

How fast will my order ship?

Place your order by 2:00 PM EST for same-day shipping! Orders received after the cutoff ship the next business day.

Standard Shipping: 3–4 Business Days.

Next Day Shipping: 1 Business Day.

Please Note: Delivery dates are estimates. While we ensure timely dispatch, we are not responsible for delays caused by the courier. Additionally, customers are responsible for the cost of reshipping any orders returned due to incorrect address entry.

What if I entered the wrong shipping address?

We ship to the address exactly as entered on your order, so please check it carefully at checkout. If you need to correct it, contact us at info@swiftronics.tech with your order number right away — we can only update an address before the order is fulfilled. Once a carrier confirms delivery to the address on the order, we are unable to recover, replace, or refund the parcel, and carriers do not accept claims in these cases. Parcels returned to us as undeliverable, refused, or unclaimed are refunded less original shipping and any carrier return fees.

Nothing here limits any right or remedy available to you under applicable consumer protection law that cannot be waived or limited by agreement.

Do you ship across the United States?

Yes, we ship across the U.S., including Puerto Rico, Hawaii, and Alaska.

Who do you ship with?

We partner with a variety of reliable couriers to ensure the best service based on your location and chosen shipping method.

Signature Requirement: For your security, all orders exceeding $250 USD require a signature upon delivery.

Hold for Pick up: To ensure the safety of your shipment, we reserve the right to hold packages for pickup at your local courier depot at our discretion.

What is your return policy?

Returns must be started within 30 days of receipt, and return shipping is paid by the buyer. If the item has been used or shows signs of usage, a restocking fee of no less than 20% of the original purchase price applies. Swiftronics reserves the right to inspect any item before approving a refund.

At Swiftronics we offer a 30-day warranty on all our international devices, issued as a repair, or a replacement if a repair is not feasible. This warranty applies to product defects and failures only. Warranty claims made after 30 days are redirected to the product manufacturer and are subject to the manufacturer's policies. Under no circumstances will liquid or physical damage be covered by warranty.

How can I leave feedback for Swiftronics?

You can leave feedback on any of our social media platforms. We’re connected via Facebook, Google, Instagram & Yelp.

Do you offer an Extended Warranty?

Yes! Swiftronics partners with SureBright to offer comprehensive extended warranty programs. These plans go beyond standard manufacturer coverage to include both mechanical breakdowns and accidental damage, such as drops and liquid spills.

Duration: Coverage typically ranges from one to three years, depending on the specific product.

How to Purchase: You can view available protection options directly on the product page of the item you're interested in.

Post-Purchase Window: If you didn't add coverage at checkout, you have up to 30 days after your purchase to add a protection plan.

Purchases of additional warranty coverage are non-refundable.

Do you Price match?

Yes. If a US retailer has a lower price on the identical item, we'll match it at the time of purchase.

To qualify, the item must be:

  • Identical: same brand, model number, storage, color and version. A Global model is only matched against the same Global model.
  • Brand new, in stock, and sold and shipped by the retailer itself.
  • Publicly advertised in US dollars when you ask. Sale prices count.

We don't match:

  • Independent third-party sellers, dropshippers, peer-to-peer marketplaces, or open box / liquidator sites.
  • Clearance, liquidation, or doorbuster and limited-quantity deals.
  • Pricing errors, bundles, financing or gift-card offers, and coupon or member-only prices.

How to ask:

  • Call 1-866-863-7010 or email info@swiftronics.tech with the link before you order. Once we verify it, we'll send you a checkout link at the matched price.
  • All price matches must be made and verified at the time of purchase. We can't offer retroactive price matches or partial refunds after an order is placed.
  • We match the item price before tax, one unit per item per customer. Brand-new items only.
Does your In-Store pricing differ from your Online Store?

Whether you choose to buy online or in-store, the prices are the same.

What is a Swift Certified (open box) item?

SWIFT CERTIFIED is our category for open-box products, including customer trade-ins and returns due to buyer’s remorse. Every device goes through a multi-point technical and physical inspection, and comes with an extended 90-day Swiftronics warranty. You can add 1–3 years of extra coverage through SureBright at the time of purchase.

Open box devices may not include headphones for hygienic reasons, and may have minor cosmetic differences compared to brand-new units. Open box devices are final sale.
