Coupon 101: Doubles

One of the biggest deal diva secrets is doubles! Now living in the Northwest, it is not as easy as it is in other regions of the country, but doubles still exist and with planning you can score free or cheap products. Stores that double and their "rules"...

1. Safeway, up to 50 cents per coupon, up to 4 per transaction. You just need to hand them the double coupon that is in every ad, every week.
2. Albertsons, up to $1 per coupon, up to 3 per transaction. Hand the cashier the 3 double the value coupons that appear periodically in the weekly ad or a special Sunday insert.
3. Kmart, periodically double events. The last one was up to $2 and limit of 5 per day. This was a Shop Your Way Rewards event, tracked by your rewards card.

I really hate the limit per transaction rule at Albertsons and Safeway. I would much rather they just had a doubles day or something, but alas the rules are in place so it doesn't get out of hand. What do you think, do you like doing numerous transactions to use numerous doublers? Do the cashiers give you a hard time about this?

Note: I have heard of "tripling" coupons, but have yet to see this in the NW :(
