We did this deal this morning. We consolidated our 2 $300 gift cards (1 $600 gift card) and had 2 $50 promo gift cards (you cannot consolidate these with the regular gift cards). We were able to use our $600 gift card, and *1* of the $50 gift cards, then our credit card to pay the balance. The agent we talked to let it slip that we could use up to 3 cards of any type, so if we had purchased one of the gift cards for $473.99, rather than $300, we should have been able to use both of those (combined into 1) and our 2 $50 gift cards. ($473.99 was our balance (with tax) after using a $300 gift card - you can figure out your balance by going through the checkout online.) Oh well, at least we saved $50 on a TV we were going to buy anyway and now have a free $50 to spend online at the Dell store! Thanks for posting the deal.
