No help on Amazon.com Noté 2 sur 5 étoiles
This review is only about how PriceBlink behaved on Amazon.com. (That was so discouraging that I didn't try it anywhere else.)
During a browsing session on Amazon, PriceBlink showed lower prices for only 6 of about 40 items. The "best price" for all the other items was higher, mostly by $2-3. In one case, PriceBlink showed a best price of $17.28 for an Amazon item priced at $2.98. The 6 items for which PriceBlink did show lower prices were very cheap anyway -- Amazon price $2.50-4.00 -- and PriceBlink's lower price was only a few cents less.
Not a keeper for me.
If I understand you correctly, you're wondering why PriceBlink shows prices that are higher than the price shown on the page you were viewing. If so, that's because you've already found the lowest price on that item.
PriceBlink checks prices from over 11,000 retailers whenever you're shopping. If a lower price is available, it will show you those prices. However, if you've already found the lowest price, PriceBlink confirms that you've found the lowest price, and lets you know where else you can buy the item. This is helpful in the event the product you are viewing is out of stock or you discover additional shipping charges after adding the item to your cart.
If you're disappointed because PriceBlink couldn't find a lower price, please realize that we don't set the prices -- we merely scan all the prices available on a product and let you know who has the lowest price. If you feel like we missed a lower price that we should have reported, please contact us at email@example.com so we can investigate.
