I do the same as afan. I cash out the first card as the Visa gift card since it is 2175. I use it on Sam's to buy Disney GCs (I usually have two Visas, one from my account and one from my husbands) so a Visa fro 2175sb is better than a
Walmart gift card for 2200sb for me. Your first gift card of the month is discounted to 2200sb except the Visas being 2175sb.
Then I cash out a $25 Paypal every time I hit 2500sb, until the next month. This will put $25 in your Paypal account (which will take a few days) and then you can move it to a bank account. So I put it in my savings account and then I use that cash towards my vacations. This is because I can usually get better rewards with my credit cards than the 2% savings of 2450sb for a Visa gift card. And then I can also combine that with other savings, like if I can get a discount on a Disney gift card somewhere or buy it at my grocery store to earn fuel points. I also may just use that cash for actual vacation costs that I can't use a Disney gift card for. I don't like to sit on Visa, etc gift cards either, and I've heard the virtual visas from Swagbucks can be hard to use in store in person, though I've never tried.
I combine all my Disney gift cards through the Disney gift card website, moving the money on to an older Disney gift card. I also don't leave them loaded in my account on that website in case someone would get into my account.
