You know I am with you on this. There should be some sort of state law that prohibits retailers from doing this after a set and reasonable time period and I feel that waiting 7 days is an UNreasonable time period to find out that there is a pricing error and you will not receive what you paid for. After 7 days you would assume that the items were on the way to be shipped.

The retailer has the responsibility to ensure that what ever item is placed on the website is the true and correct price for that item. Otherwise it might be considered false advertising.
