I understand your frustration. I was ordering last week online with a well known shop and on the last selection the All the prices changed dramatically in the cart. Thought that it was something I had done so I went back and checked the prices on the first pc and it was doubled. Needless to say I canceled the order. I checked my e-mail alert that I had received prior to the sale to make sure that there was not a specific time table for the sale and it was supposed to be all day. Go Figure! Glad it was just stuff I wanted not needed.
