Old Navy Gift Card Deal

I was just loading coupons onto my Smiths Card and I found one of my favorites. $5 off $25 Old Navy gift card. If you like to give gift cards for Christmas or birthdays, this is a great deal for the obvious reason, but the reason I love this deal is because I buy them for future use. If you like to shop at Old Navy, you just got an instant 20% off, it's a gift card so there's no rush to use it, AND you can combine it with a coupon or discount because when you use it, obviously, it's just a regular gift card!! I bought some at Christmas when Vons had a similar deal, and I just used one the other day for Uniforms for my kids and I'll probably use the other one at Christmas. I'm not sure if you can buy more than 1 per transaction because it doesn't say on the coupon. I'll try and find out and let you know.
