Swagbucks discounts the first $25 gift card you redeem each month to 2200SB. Any additional gift cards redeemed that month will cost you 2500. For this reason I think most of us do get a gift card for the first redemption. After that it varies, some people just cash out for Paypal and others continue with gift cards.
There is a slight advantage with the Target cards in that you can get the additional 5% discount online using them with your Redcard; same with
WalMart (4.68% discount using them at Sam's Club). So if you buy either of these cards your money will go a little further, but a lot of people just prefer the cash.
