I use VISA gift cards for everything, which kinda work the same way. Once you register them, they work just like regular VISA cards. The only problem I've had is that they're limited to US purchases only. I have them in my PayPal for eBay purchases and most of the time international orders go through, but once in awhile you run into an out-of-US vendor that has their account set up funny. It's only happened to me once - a vendor in Canada. For gas, you have to prepay so that you can specify exactly how much you wanna charge. If you do the fill'er up thing and just swipe the card, it will pre-authorize an amount that might be more than your available balance. I do this for the stack of gift cards that get ridiculously low and hard to use - "$4.67 on #4, please."I know in the past there have been problems with those visa cards for online purchases and using them at gas stations. I'd look into that JoAnn before you go that route. If it works, let us know!
Sandy - beautiful flowers!
I go with gift cards instead of refillables because refillables require your Social Security number, and gift cards don't.
