Walgreens Register Rewards

Had a few questions this week on the Register Rewards at Walgreens.  Just so you know, you can't use a Register Reward on an identical item.  For instance, say I buy two razors on separate transactions.  I get a $5 RR on the first razor.  I can use it for the second razor, but it will not print out another RR for the second razor because I used a RR on it.  If I would have not used the RR on the second razor, I would have gotten another $5 RR.  Thought I'd share this little tip so you get the most out of your money.
