I suspect we've all been here at one time or another.
I went to Lowe's with the idea of buying a Porter Cable compact belt sander ( 2 1/2" x 14" belts). I first checked the bin for replacement belts, but they didn't have any. The aisle associate checked the computer and assured me they were coming in on the next truck. However he wasn't sure if they expected one belt or one package of belts.
I voted with my feet.
