I used to sell (vintage clothing a and housewares) on eBay in college. Mostly to support my thrifting habit. :P But I don’t have the time and patience for that anymore.
Now vintage clothing goes to a local vintage shop. They buy the whole lot based off of what they think they can sell. And they donate and textile recycle the rest. Housewares goes to another vintage shop. Vintage furniture goes on Craigslist.
Non-vintage clothing goes to a resale shop. Toys go to a new and used toy store. Random items go into a corner in the garage for a future garage sale.
I think it helps to have an urban market. I live in the Bay Area and CL seems way more active here than in less urban areas.
