Thanks Dan and everyone else who participated with positive comments.
Alan, I can guarantee the gift cards will be new. I can meet the person at the store and they can watch as new gift cards are issued and handed directly to the buyer. After that, I have no clue what can or can't happen with any type of gift card from any place that someone buys from. Personally, I would rather have slightly less cash than a gift card since they can get miss placed, lost or stolen if you are not as careful as you would be with cash. For example, I might leave a gift card in my car but I wouldn't leave cash in there. I might be getting too many cards in my wallet and take some out and forget where I put them or they somehow find their way under the kitchen appliances.
Most of the times where I have made deals regarding store gift cards such as Tiffany's the buyer just went on a shopping spree. Then I just used the gift cards and paid for their stuff and they just gave me the cash.
I talked to a lady at the Pawn shop and she said she would pay 45% for certain items(gold) that were NEW as long and I brought a sales slip in my name. That way she could sell the item as brand new.
