I received a gift card of $ 150 and I do not know how to use it, they told me that when I checked out any purchase I would have the option to exchange it but I already tried Ebay, Aliexpress and GearBest but none of the space appears claim the code, I only see the options to change account (paypal), change the payment method (which I can only choose credit / debit card) and cancel the purchase. help please if they tell me what I do wrong or at least on what pages it works. Beforehand thank you very much.
