Return & Refund Policy

Once sold not refundable, unless

  • EastShore fails shipping your order due to EastShore’s liability
  • Or, product received is significantly different from what advertised due to EastShore’s liability(submodel switch doesn’t qualify for reason to refund)

Register an account on the site, add products to cart, fill your desired quantity, choose destination country, shipping cost and total price will show. Follow the system, payment options and related info will show. After placing an order and payment made, you will receive a confirmation email and your order status will be changed to “awaiting shipment”. Your order status will be changed to “shipped” when tracking number is assigned for your order. You can review the status of your order at any time in your user account.



  • Prices of products on the site are in a USD value. The price of bitcoin mining machines has to be adjusted frequently in accordance with variables such as BTC value and market circumstance. Refund requests based on price changes cannot be honored. The payments for orders are accepted through the Bitcoin (“BTC”) payment network and other options such as wire transfer. In the event you choose to pay in BTC, the site will calculate and convert the USD value to BTC amount according to our chosen exchange rate (which is a weighted average from major Exchange sites around the world). Later changes to the exchange rate of USDBTC have no effect on the amount to be paid for your placed order.
  • On occasions, the submodel of products could be changed before shipping. In that case, the buyer will be informed. And if there is any price difference, we will refund the difference if the submodel is switched to a lower version; we will ask the buyer to make up the difference if the submodel is switched to a higher version. The switch of submodels will not be honored as a reason for refund.



All purchases are final. Request for refund will not be honored by us. We advise you to make any payment only after careful consideration. In the case that we fail to ship out your order, we will contact you for refund.  Generally, refund will be in USD with the USD amount of your order amount instead of the BTC amount, considering USD is a fixed amount, not a variable like BTC.



  • All prices for products sold by us and invoiced by us to territories others than People’s Republic of China are entered without value added tax and customs duties. You are solely responsible to consult your state and local tax laws to determine compliance with tax laws and regulations in your area and pay the taxes and duties if applicable according to your tax residential law. We are willing to provide assistance within our ability for your customs clearance though.
  • We reserve the right to change the declared value requested according to customs circumstances.
  • If the buyer fails in customs clearance, or shipment is returned or abandoned, the order is not refundable. If shipment is returned, we will resend the returned shipment under the circumstances that the buyer pays fees incurred within a week the returned shipment is received by us.
  • EastShore does not take any responsibility for or compensate for any loss as result of downtime caused by delays in transportation as a result of custom formalities or other reasons.



Delivery will be arranged after the order is fully paid. Delivery service is provided by third parties such as the national post services or international express shipping couriers such as DHL, UPS, FedEx. The international express shipping couriers are usually door-to-door services. Please note that we may choose a different service (an optimal option on the occassion) rather than the option as displayed when you placed order.

  • Delays due to manufacturers’ production capacity are not qualified for order cancellation or refund.
  • Delays due to customs reasons, wars or any other contingencies beyond the EastShore’s control are not qualified for refunds.
