Let me introduce you to the GiftOga Platform - www.giftoga.com

GiftOga is a Gift card processing platform & marketplace. You can buy or sell gift cards on the platform depending on your account type. You can check out the platform here .

The account types are for Personal, Merchant, Corporate and Agent.

a). Merchants: GiftOga makes it possible for merchants to generate and sell their digital gift cards. It puts money into their hands even before the gift card is redeemed and hence, improving their cashflow.

b). Personal: Individuals are able to buy these gift cards for themselves and/or their friends.

c). Corporates: Businesses are able to buy the gift cards in bulk and use them to incentivize their staff and appreciate their customers.

d). Agents: Agents are able to earn money by reselling the available gift cards via our app directly or via API integration.

Both local and international gift cards like Amazon, Google Play, Steam, Apple Store, Adidas, etc are available for purchase.

Giftoga.com is very much a great market place to purchase giftcards, I just ran through their payment method but they don't accept cryptocurrency. Similar site like buysellvouchers where I trade accepts crypto and also offers good discount rate
