I recently purchased something from an internet retailer. The item was described as "SOUND BLASTER LIVE SB0222 PCI SC 20PK" and as you can see it notes, a 20 pack. I purchased this item for $40.40 - Quantity of 2 - Total: $80.80. This internet retailer billed my credit card for this product, then e-mails me and says that there was a "technical glitch" and the wrong price was noted on the site. Are they obligated to finish this transaction? From what I have been hearing, once they bill my credit card, the sale is complete and they must go through with the sale, is this correct? Please reply - Thanks!
