I used to go all the time and we used our Saturday community sales for exercise by walking all around. Hubby had ebay business in books and we were always looking. No more. Sales are farther apart, he stopped ebay sales and I have no room for more junk. I do watch ads for estate sales, fabric sales, etc. But I am much more selective.
Even with this careful looking, I still find great buys about 4 times a year. One time it was an ad on my guild's facebook page, another was an ad on Craigslist, etc.
