yup,,,,buy and sell stuff,,,not alot,,,,but no issues.
Have bought small and big items,,,tools,,,guitars,,,,car parts (bumpers, trim, misc),,,,usually no issues except the occasional hiccup,,,(usually with a buyer that flakes out)
Pretty easy way to "clean out" the garage and make some spare $$
Shipping is something to watch,,,both from a buyer and seller perspective,,,,some people really jack you on the shipping costs (almost a way for them to make up $ on the selling price of the item),,,,,
if your selling stuff,,,have a rough idea on shipping, costs,,etc,,,so you dont get burnt or stick it to someone.
my buddy buys alot of tools off of craigslist,,,,usually local,,,easy to pick up,,,no shipping costs,,,and most people end up throwing in more tools,,,,"just to get them out of the garage",,,, he has made a killing collecting snap on stuff....... quite a collection.
