I got a C128 and disk drive for $35 in the boxes in a Cinncinnati Ohio thrift store in the 90s.(still have it.)
And 8 C64s at another one for 50 cents each.
Had so much C= stuff that I got rid of most of the boxes and packing to make room in the house;then found out people on eBay would pay double for original boxes!
C= should have made JiffyDos standard and sold even more C64s.
