Rite-Aid has joined the others, and this week is offering a $20 g/c for any transferred prescription. Grab your local paper, and check it out. They also have a price match or better guarantee.

This is the first national offer I've seen; the local grocery pharmacies still have $20 for transfer, and even an $80 glucose monitor.

Rite-Aid also generally gives out general use g/cs, like Discover cards, so they are much less limited.

Rite Aid is also offering:

$25 worth of money saving coupons right away
