I pre-ordered The Social Network the other day for $22.99 and today it was lowered down to $16.99. I know I'll get the price, but when I look at my order details the price of the item hasn't changed, it's still $22.99. Also, the majority of the order was purchased using both a promotional code and a gift card (about $4.00 was left that I needed to pay with a debit card). Will that cause any issues with getting the new price and/or getting a refund for the difference of the prices?
