I went and checked the double coupon event out:

1. All it takes is scanning your “shop your way” rewards card to have the first 5 coupons you hand the cashier doubled, up to $2.00 per coupon, per day.  You can sign up at the store if you don’t have one.
2. You can not use 2 identical coupons (so you must mix up which products you buy).  I have heard you CAN in other states, but not in Utah.
3. The $10 Prepaid Mastercard Rebate does not print upon checkout – you must find the rebate forms hung up in your store. Mine were on an end-aisle near Pharmacy.
4. The rebate states $25 can’t include taxes.
5. *The rebate doesn’t state whether or not you can use coupons before or after $25, and attempts to call the phone # on the rebate form lead to no answers.
6. The $10 Prepaid Mastercard is 1 per household, no p.o. boxes.
7. The $10 Prepaid Mastercard Rebate is valid on the following brands: Align, Always, Aussie, Bounty, Bounce, Braun, Camay, Cheer, Clearblue Easy, Covergirl, Crest, Dawn, Downy, Dreft, Duracell, Ear, Eukanuba, Febreeze, Fixodent, Gain, Gillette, Gleem, Head & Shoulders, Herbal Essenses, Hydrience, Iams, Infusium, Ivory, Joy, Luvs, Mr. Clean, Natural Instincts, Nice & Easy, Olay, Old Spice, Oral-B, Pampers, Pantene, Pepto-Bismal, Prilosec OTC, Pringles, Puffs, Pur, Safegaurd, Scope, Secret, Swiffer, Tampax, Tide, Vicks, Zest
