The #1 issue is not how the lure you to the site, nor the cost of the bids. This #1 issue is all the reviews by winners who never receive their items. When you contact them, they make excuses and never give a ship date.
The #2 issue is the mental health of the customers. Why do they keep bidding and throwing money away when they don't receive a single gift card, jewelry item, or electronic? The only items they do send, on rare occasion, are the useless florida or mexico trips, or the valueless $50 e-cards where the only thing you can purchase with it is a cheap ice cream scoop you could have bought at the $1 store.
