Sainsmart Terms of Service


Return products you are unsatisfied with.

If you are not 100% satisfied with your purchase, you can return your order within 30 days to the warehouse for a full refund. Please contact us for the return address. Customers are responsible for all return shipping charges. Once your return is processed, you will receive a refund for the amount paid to your original method of payment.

Return the wrong item.

If the item you received is different from the one you ordered, please contact Customer Service with photos or videos of the product. If a return is necessary, replacement plus shipping cost will be issued to you upon receiving the returned product. If you decide to keep the item, we will offer a 10% discount, and will send the replacement product to you.

Return defective items.

If your product is defective with physical damage you may return it within 90 days of the initial shipping date. You may mail the item back in the original packaging without any wear or tear for a free replacement. However, you will need to provide photos and videos showing the defect(s) of the product.
*NOTE: We strongly recommend obtaining and saving your return tracking number until you are notified that we have completed your refund.*

When will a replacement be sent?

Replacements are treated the same as new orders -- they typically arrive in 10 to 13 days. If a product needs to be returned for replacement, the replacement is sent after receiving the returned item.

How long do refunds take?

It may take 1 to 2 weeks for your return to reach our warehouse. Once it is received and inspected (usually within 72 hours of receiving) your refund will be processed and automatically applied to your credit card or original method of payment within 2 days. Please note that depending on your credit card company, it may take an additional 2-10 business days after your credit is applied for it to post to your account.

Payment Methods

We can accept your payment in various ways:

Credit Card:

All major credit cards (Visa, Mastercard, American Express, Discover) are accepted through our secure payment processor Authorize.net. It provides top-notch fraud protection for you by screening orders for potential fraud. Please ensure that your billing address matches that of your payment method to avoid delays in order processing. Sainsmart does not see your credit card number when paying with a card through Authorize.net.


With PayPal, you can pay through your PayPal account, credit card, debit card, or via bank account transfer. Once your order is submitted, you will be redirected to PayPal's site where you can make the payment. We don't see your credit card number when paying with a credit card via PayPal. It is safely encrypted through PayPal's server, which limits the risk of unauthorized use.
