Online

We accept a variety of payment methods, including most major credit cards and popular forms of payment. Accepted payment methods may vary based on country and type of order.

    • Estripe accepts VISA, MasterCard, American Express, Discover, Diners Club and JCB. Your credit card is charged only at the time of the actual shipment of item(s). However, there might be a temporary hold on the funds until the time of actual shipment. If paying by Debit or Check Card, the funds are authorized as soon as the order is placed, which may affect the availability of funds in the account.

    • You may have heard that we are now accepting Dogecoin, but did you know that we also accept Litecoin, Binance coin, Ethereum, Bitcoin, and other cryptocurrencies? In fact, we’ve been accepting digital currencies since 2018, when we were the first major retailer to accept Bitcoin as a payment option.

    • Bitcoin is an experimental, decentralized (not controlled by any organization or government) digital currency and peer-to-peer payment network that is powered by its users. Bitcoin is like cash for the Internet.

Our vision of diginal currency

Bitcoin is one of the most important inventions in all of human history. For the first time ever, anyone can send or receive any amount of money to or from anyone else, anywhere on the planet, conveniently and without restriction. It’s the dawn of a better, more free world.

Let’s face it, we are living in the next big revolution, and it is just getting started. Many challenges surround the real world use of cryptocurrency, but on the positive side businesses are beginning to embrace this technology.

Now that our company accepts cryptocurrency as a payment method, we are setting a precedent for Bitcoin and other cryptocurrencies. We’ll continue to be a driving advocate and supporter of the cryptocurrency industry as it continues toward mainstream market adoption.

Product Warranties

Products sold on Estripe are generally covered by both Estripe’s return policy and the product manufacturer’s warranty. Details are listed under the Warranty tab on each item’s product page:

Backorders cancellation/return policy

Orders containing both backorder and in-stock items may have the backordered items canceled at the customer’s request. Backorder cancellations and/or modifications must be requested no later than seven business days prior to their release date. Cancelling backordered items may result in a 5% cancellation fee. Refunds, minus the cancellation fee, are issued through the original payment method.

In some circumstances, you can be charged a restocking fee when an item is returned. These circumstances include when an item is returned outside of Estripe’s return policy or in used, damaged, defective, or materially different condition. Items returned in original condition and within our policy guidelines cannot be charged a restocking fee. We are not required to accept returns beyond the return window. However, if we do, you can also be charged a restocking fee.

A restocking fee is a percentage of the item’s price, depending on the type of item and its condition upon return (item price does not include shipping costs). Only returned items are eligible for a restocking fee. The refund workflow will help you calculate the restocking fee for eligible items, and deduct it from the refund you issue to your customer based on the guidelines outlined in the table below.
