Like a password stuffer, except for active coupon codes.<p>I worked for a website which had various weekly coupon offers, sometimes very great deals. They also used generic "coupon1,2,3" codes on the backend, still active on the live site to archive the various specials. When the specials get deactivated, the coupons1,2,3 all remain active.<p>Just so if you say, go to totallyawesomemugs.com and want to buy a mug, you see "coupon code" in the shopping cart so... 5% off is better than no % off, so i wouldn't think this wouldn't be really that blackhat if the coupon codes are active.<p>I've seen old website password stuffers ages ago, which is why i ask if there's an app/plugin like this for possible discounts in shopping carts.<p>I've used "Honey" before as a plugin, it didn't do much that i could see, just randomly try codes that expired or never existed in the first place.
