There's all kinds of stuff here from unusual hardware items, computer paper, automobile tools, furniture, rugs, books, CDs, collectibles and so one. Mostly, the prices are very good. The stock is constantly changing in typical flea market fashion.
My best find: a pint of Jacobean wood stain from MinWax, last produced maybe 20 years ago.
It's worth a drive to Bedford and an hour or so just to snoop around.
