I just came from Copps, where the cashier told me it was DOUBLE-double day today, 5/21/2011!
This means you can double up to 10 coupons per transaction (All other doubling rules apply. See details here & check in with your store's customer service desk to verify.) I'm guessing this applies to all Copps stores today, but can't be sure. So, check in with your store!
Not knowing about the double-double day, I had prepared two transactions (using 5 doubling coupons in each). However, I accidently placed one product in the wrong transaction. Luckily, the cashier noticed this. So, I ended up checking out with four doubling coupons in one transaction and six in the other. They all doubled!
Maybe I would have purchased more if I had known ahead of time! Not sure I'll make another trip back again today, though...we'll see.
Stay tuned! I'll be posting my actual Copps trip from today & two trips from yesterday (Hy-Vee & ALDI) soon!
