Walgreens Register Rewards

Very exciting news!!!  I went to Safeway today in the Springs with my Walgreens Register Rewards in hand.  And they took it, scanned it, and no issues.  Very exciting I usually try to avoid getting too carried away with Register Rewards because they are so hard to use at Walgreens but now I'm going to be all about them.
Have you tried this yet?  Did you have success?

But there has been another change at Safeway to be aware of.  You can only use 1 printable per item.  So don't waste the ink unless you plan on making multiple trips.
