For the Walgreen's Register Rewards, you can use them just like cash on your next purchase (or on your next transaction)! You can combine them and use them for whatever you want (though your best bet is to use them for something that will earn you more Register Rewards).
As someone who just discovered the great deals at CVS, Walgreens and Rite Aid, I am estatic about these places! I have been stopping at at least one pharmacy every evening after work for about 2 weeks now, stocking up on items. At first it was hard to figure out how to get the best deals, but once I did I am sooooo HOOKED! It takes a lot of organization and planning (your shopping trips) to get the best deals, but once you figure out how to combine store sales, manf. coupons, store coupons, reward programs, etc. it's so addictive. Most items I have been buying I get for FREE and some items they are even paying me to buy them! It's crazy... I have no idea how these places make money!!!!
So far, though, my favorite is CVS. They have the best program, I think, with their Extra Bucks. Plus, I find that CVS is generally easier to deal with.
Well, have fun shopping! I am stocked up on enough toothpaste, toothbrushes, soap, dishwashing liquid, shaving cream, razors, etc. to last me 6 months! And I have only been shopping these stores for 2 weeks!!!!!
God bless,
