Here's the post:
DeCA started the program about six months ago, and it's now rolled out worldwide. It's similar to other grocery rewards cards, except that the coupons are on DeCA's website. You log on with your reward card number, browse the coupons, click on the ones you want to "clip", and that data is linked with your card account on DeCA's website.
When you get to the commissary cashier, you scan your card. The register reads the coupons on that card number, automatically checks for the items as you're rung up, and credits your coupons at the end. Just like a regular paper coupon, only lots faster and with less back-office infrastructure at the commissary.
I'm not an extreme coupon shopper, but I really enjoy this system. It doesn't replace paper coupons (yet), but it's saved me lots of time in organizing & tracking. (I also don't have to use a magnifying lens to read the fine print or the expiration dates!) I don't even bother searching for paper coupons anymore unless they're right on the shelf next to the item. I think that manufacturers are eventually going to cut their costs by going to electronic systems like this, and paper coupons are going to dwindle significantly over the next few years.
By the way, you don't even have to bring the card to the commissary for scanning. You can store the card number on your phone and give that to the cashier...
