If you have any prescriptions fulfilled by the Walgreens pharmacy you could get a $10 Walgreens store credit. All you need to do is refill that precription online on Walgreens.com. Full instructions on how to do that here.

Every time I transfer my RX away from Walgreen’s (to take advantage of another pharmacy’s $$ for transfer) Good old Walgreen’s insists on sending me a letter begging me back and with an enclosed check for $25 (must use it all at once at the store–no gift cards) but hey…if they want me back who am I to argue with $25?
Note that this $10 needs to be redeemed online only, not in stores.
