i know that hancock fabrics have those kind of sales..i recently purchased two packages of treadle sewing machine bobbins (hard to find) for 90% off costing me less than $5.00 total... i am a dumpster diver every chance i get..and i love antique and junk stores...my sister in law and i go "junking" pretty regularly and you would be amazed at the treasures we find as well as the repair, repurposing, and recycling that we do. seems to me that stores that behave so bizarrly as to throw away perfectly good items would at least get fair tax credit for donating...and discounting at 90% still makes them a few cents on the product..
