it gives a discount (cashback) to the buyer of eBay auctions. the
discount is 36% of the fees eBay charged the seller of the item you
won. this can add up to be quite a huge discount. you also make money
off of the people you referred when they shop on eBay. it is a good
way to make TONS of money if you are an eBay PowerSeller (by referring
your buyers/link in your auction), but it can also save you a good
amount of money if you are just a buyer. bigcrumbs has been around in
the US for a few years and many people make $100-$2000/month easy.
bigcrumbs is 100% free. use my referral link before you sign up
