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?
