I'm very cautious about garage sales, and most particularly about estate sales. I advise that BEFORE you go out to estate sales, watch a few episodes of HOARDERS-type reality shows; then also do a short search on "senior hoarding" at google, and learn that it is a big and ever growing problem in this nation.
I advise to be VERY careful what you purchase used or secondhand, particularly at estate sales for you never know if the original owner was a packrat who purchased that "brand new" looking only 25-cent bottle of shampoo over a decade ago and added it to their stash of 326 bottles of shampoo.
With the exception of books and dvds/cds, I don't purchase anything used UNLESS I can fit it into my washing machine and launder it --- or in some way totally submerge it in soapy water and totally sanitize it.... like dishes.
I didn't realize that some of those very well organized estate sales which were bursting to the seams with 1000s upon 1000s of items still in the original packaging with tags were representative of a deceased hoarders' filthy MESS - NOT indicative of a "collector" and were obviously professionally cleaned up by the estate sales company conducting the sale.
Since craft items are invariably on the list of "most frequently hoarded items" I would never buy them at an estate sale because who knows how old they are and what conditions they were stored under. Ditto for containers of any type, bags of any type, and magazines. (They are always mentioned in articles about hoarders, LOL)
Watching all the many documentaries about hoarding has really turned me off to the re-sale market and to thrift stores in general and made me VERY cautious about what I bring into my home.
