Well, it's new to me anyway! E-Centives is a printable coupon site with tons of great coupons - Betty Crocker, General Mills, Yoplait... all the usual suspects. They have a lot of the same coupons as coupons.com and couponbug.com, which is great for multiplying the amount of like coupons.
But here is why E-Centives is better...
NONE OF THEIR COUPONS SAY DO NOT DOUBLE! At least, none of the ones I've printed. :)
We all cringe when we see this horrible black bar across the top with huge, blaring letters saying "Do not double or triple." It kills deals! Even though it's coded with a 5 and will automatically double, if a cashier sees this wording, they are technically supposed to suppress the double (by pushing a button on the register). Sometimes, the cashier will just scan it, allowing it to double, but you never know! It's a total crapshoot and it makes planning shopping trips really difficult!
