My inner cheapskate is thrilled to know that, as of today, I will get 30% off at AMC Theatres and - be still my heart - 10% off at Arby's, IHOP, Wendy's, Dairy Queen, Hardees and Long John Silvers. (Hopefully, the deal will extend to cholesterol meds.) Not to be outdone, Jiffy Lube will discount me, too. Membership in the double-nickels club does have its privileges. I'm just hoping someone will ask for proof of age. I haven't been carded since 1984.
