Only offers amazon gift cards at ridiculous amounts (1, 2, 5, and 10 dollars only). The miles needed to redeem are ridiculous (10,500 miles for a $2 gc). All the other offers seem designed to be attempts to make up for the non-existent variety of gift cards, and are also low quality uninteresting "rewards" (think samplers and free trials for random things you'd find on rewarded survey websites). The bidding for cards is the same price as buying them, except for lower chances of winning. Bad app.
