You have 4 sets up for sell, and there are 0 other sellers on your site. Also, there is no search bar, so as people list stuff you just have to scroll through 1 page dedicated to EVERYTHING listed on your site. This is extremely poor UI. Your "Why we started" page has grammar errors, and can you at least LINK me to your eBay store so I can have some reference.
I can see that Carlos has sold something, but I can't seem to find what he sold or how much he sold it for. So this appears VERY fishy.
This is so OBVIOUSLY a scam. All your tabs at the top of the site just lead to each other, and NOWHERE on your site do you even EXPLAIN how it works. On your 4 items for sell, I don't know who the seller is(I am guessing you) and if I list something will it just be thrown into your list of items for sale. With no search bar and NO FILTERS, I am to assume that everything that is listed is thrown into ONE HUGE LIST, with NO WAY of organizing it. If there are 10,000 items in your store nobody and I mean NOBODY will scroll through them all, however is numbered 10, 000 will never sell their items. Sales with fees are better than no sales with no fees.
I have seen tons of scam sites x10 better than this, but if it is your first scam site then I can tell you are still working out the kinks!
