Walgreens

So I'm still learning this Walgreens thing. How to roll the register rewards etc. They have this lotion that is is on sale and you get a register reward for the full amount of the item. I didn't buy it last week thinking that I don't really want to spend that much out of pocket for lotion even thought I would recover my cost with the register rewards. The one thing that is good about this deal is that the register reward is a high value and only counts as one coupon the next time you use it. I was having trouble using all of my rr in one transaction because I would have too many items for the number of coupons I had, so I would have multiple transactions to pay for everything. (anyways just some food for thought)
Today I bought
Angel Soft TP $3
Purell hand sanitizer $.99
vaseline lotion 7.99
Rubbing Alcohol .89
pencils 4/1
paid with $6 in rr coupons
spent 8.32 out of pocket and got $9 in rr overage of .68

They have a dove thing I might try this week. buy 4 get a $2 rr, buy 6 get a $3 rr buy 8 get a $10 rr and basically your supposed to use coupons for everything and get out of there with overage from rr. i have to inventory my coupons tomorrow and have it all figured out before I go.
