I used to sell alot on CL back 10 years ago.
I have used Letgo to sell some house appliances (used)
But as far as new things I can't say I have. Mainly used things such as TV's, furniture, etc...
Always had a rather good experience, just some people were weird at times.
Always meet in a public area (starbucks, bank)
and daylight hours only mainly. Especially if its a high ticket item
you mean this?????
