Kathy,
A route of thrift shops, in pursuit of items that you may be able to sell on Ebay, plus a plan for a really nice lunch, sounds like a possible day "out." Be sure to call ahead to see if/when the thrift shops are open for business.
Alternative thrift shop motive: looking for special holiday gift items. In England, I bought a commemorative porcelain tea cup and saucer for my sister's collection. (Commemorating QE2's coronation, no less, lol). Or, that perfect three-tiered cake tray? A really old atlas for a history or map fiend? Jigsaw puzzles for the friends who are isolating? Weird and wonderful kitchen gadgets? Snazzy old costume jewelry for just the right little girl ? Funny tee shirts?
