I tried to buy a swing set last week and they were out of stock. The page asked if I would like a notification when the item is in. I sent a request and learned yesterday that the item's price of $499.00 increased to $999.00. I realized that this was the sale price. However, there were other swing sets that were on sale and the same time and their sale price still stands. On the page it never said that the price is only good for a certain amount of time, nor was there anything to specify that it only pertains to in stock merchandise. I have taken pictures of the swing set on sale along with the other's on sale and pictures of the other ones still on sale while the item I tried to purchased increased in price. I am entitled to purchase that item at the sale price unless otherwise stated.
