Giant Eagle's website has a link to a coupon online you can download and print.
--> Download Rx Coupon
It's worth $1 in FuelPerks -- that's $1 off up to 30 gallons of gas (a $30 value) -- when you TRANSFER a prescription to their pharmacy. At Giant Eagle, there's no limit on how many FuelPerks you can earn, so you can earn FREE gas. You also earn points for the money you pay at the Pharmacy -- at 20 cents per $50 (at least in Columbus market; 10 cents per $50 in most others). The offer online currently expires 4/3/2013. They have lately been accepting a coupon for EVERY prescription transferred with no daily limits or other hassles.
CVS will likely NOT honor the online coupon. They tend to only accept those printed in newspapers or sales flyers.
Also:
At the top right of The Columbus Dispatch (Sunday, March 24, 2013) was
an ad that
Kroger runs occasionally mentioning they'll give you
$25 in
Free Groceries if you transfer a prescription to them. They're not real
friendly about it though if you try to bring them more than one
prescription and more than one coupon (per lifetime). See details at
