The night before pick-up, but of course you're in there with all the other pickers. Keep an eye out for stuff set curbside early.
Last week, while walking the dog Monday evening, I spotted a pressure washer curbside. It was still there Tuesday evening. I was thinking about it. Friday is trash pick up, so I knew it would be gone Thursday evening. I stopped by Wednesday after work, knocked on the door and asked if the owner was trying to get rid of the pressure washer. He just smiled and extended his hand as though to say "congratulations, new owner". We chatted a bit. He got an electric powered pressure washer six years ago and hasn't touched the gas powered pressure washer since.
The pull start is jammed, so it needs some work, a winter time project.
Yeah, I dabble in "curbside shopping".
