I'll be using Zeex Their protocol lets you to buy gift cards directly with crypto and spend them with major retailers like Amazon, Starbucks, Playstation etc. with no fees. And they're backed by their sister company Zeek, which is already the biggest gift card provider in Europe, so the platform will be up and running quickly after their token sale.
Here is their website if you're interested: https://www.zeex.me/
I think, this is a cool and awesome project that would be nice to see that. And it would be nice if coins would add more retail so we could shop around the world using crypto more easily, efficiently and more safely.
