Madbid is a good website were you can get some expensive things for a low price.
My experience was good, I won a kitchenware for about $39USD(including the credits I need to expend). Madbid encourage its winners to share their experience in exchange of some free credits (that´s why you may see a lot of reviews saying than they have won).
Here are some points that Madbid could improve:
* They are not exactly a bidding place. Madbid is more like a place were you bet when all the people interested on a product will ran out of credits or they are not interested anymore. So, they can change this to make a more accurate description and avoid scam accusations.
* Include more products. They can include things like hardware tools, washers, microwave, blenders, ovens. Also they include iMac computers but they don't have PC's that really overtakes them like gamer laptops (ASUS, MSI, Alienware)
* They could have some regional/limited "auctions" to increase the possibility to win for some unlucky users or frequent users that have won that privilege.
Here are some points if you want to take a chance at Madbid:
* Don´t expect to win the first time. It is not impossible but it takes some time to understand the dynamic and way of work of Madbid.
* Expend your credits wisely, learn to say "Stop" if you already wasted a lot of credits and you just can´t won that auction, there will be more.
* You must have in mind that not all the money you expend buying credits will be lost. Madbid will give you some money back when you expend credits on an auction and didn't won. So, if you are going after a product you can try to won an auction and get it a lot cheaper or, lost some money (about 20% - 30%) trying to won an auction and then buy something in Madbid with the money that Madbid gives you back each time you don't win an auction.
Hope this helps.
