Ventes aux encheres

Sorry about the french title,but i have found a few sites who sell electrical equipement, i phones, etc, but you have to bet the LOWEST price to win, of course buying tickets to the price which suits you.

Last year I won a tv one of the modern ones for 20 euros, but it was a first time "gift".

I found another site yesterday,my question is have you ever used these sites and what do you think about them.

I've read about them somewhere a few months ago. You pay them something to enter a bid that may not actually win you the item? And I expect you give them your credit card details to join? Sounds like a thinly disguised betting site. Not exactly a scam but pretty close in my opinion. I wouldn't touch them.
