Albertsons Spend $20 / get $5 & 50 Box Tops tips & updates

I've added more coupon links & scenarios to my original Albertsons doubles post here but wanted to pass on a couple of tips.

1. There have been a few problems with the catalinas not printing out.  I had it once and so did a couple of friends.  Thanks to reader Karen for finding out & sharing the problem/solution.  The cashier must hit total before entering coupons or they will not print. 
2. Try to be sure that each transaction includes 3 items that have $1/1 coupons that are double-able.  Some cashiers will double $1 coupons that say Do Not Double, but others won't.  So be on the safe side if you can to maximize your out of pocket costs.
