Get a smartphone and constantly look at things. You would be surprised how quick things can sell. I had a PK grill sold out from underneath me even though I told the guy I wanted it sight unseen and we arranged a time to go over. I should have contacted the guy and gone there immediately.
Using the term gill doesn't always work. I use barbeque, barbecue, smoker, bbq, etc. as well. Misspellings are common as well as leaving brand names off. The PK grill just said charcoal grill in the title and best grill in the world in the description; $30! sigh....
I also use Zoomthelist but will try the other one listed as Zoom lists expired items as well. But you can search by state, etc.
Also, be persistent on communications. There are people that are really flakey on CL. You sometimes wonder if they really want to sell!
