Interesting website. I think a lot of people would be very interested if it proves legit and you expand your catalog.

Do you sell these gift cards directly or are other users submitting their GCs for sale?

Also there are two typos near the footer: "Fast Dilevery" instead of "Fast Delivery" and "insta refund..." instead of "Instant refund..." (unless is on purpose) and your back to top button at the right of the copyright notice doesn't work (at least I assume is a back to top button).
