FAQs

There is a good chance that may still be ordering from us on there, as we sell on Amazon too 😅 Amazon is an online "marketplace" with many sellers just like us on the platform. However, by ordering through our store directly, you get to benefit from discounted prices as well as phone and live chat support

Simply put, we cut out the middle man. A lot of other retailers purchase from a long chain of distributors each adding their own markup and ultimately making the product more expensive. We source our products internationally directly from the brand keeping our costs low so we can pass the savings on to you. All items are guaranteed to work perfectly in the UK 🇬🇧 This means you get top-quality electronics at unbeatable prices, without the big retailer markups!

Absolutely! We use trusted providers like PayPal and Shopify Payments (including Google Pay, Apple Pay, and Shop Pay) to keep your payment info safe. These methods have strong encryption and fraud protection, so you can shop with confidence!

If you place your order before 2pm (our cut-off time for same dispatch) you will get your order the following day. The only exception is if you place your order on Saturday/Sunday (as we do not ship on weekends). In such cases, we will dispatch it on the following Monday and you'll get it by Tuesday.
