I have a few times while on the road for work and I need to dump before I fly home. You can check online which location offer what gift cards. For some odd reason they don't all offer the same thing, like the walmarts I have been to do not offer overstock.com or amazon.com. I buy enough stuff online that I am not worried about using them. I also tell anyone in my family if they are going to be buying anything large to let me know. I'll dump and use the gift cards and then have them just write me a check. My parents just bought a new TV and stand so I bought it from Amazon for them, $1800 in halves

Me and my wife needed a new vacuum so a new Dyson D25 Animal is on the way from Overstock.com, $500 in halves
I figure the less I have to dump at my local FCU's the better. I also spend halves on all the shipping we do, groceries, gas for my wife and I, and a lot of thing that I buy at Walmart (household stuff and groceries). The Walmarts around me take halves in the self checkout machines
