I have freecycle and recycle sites from my local area and there are people that you can just tell are looking for freebies either to use or sell. Almost daily you see people asking for computers,printers,laptops etc for their kids.
Here are a few examples:
Wanted: household items
any household items such as a tv, microwave, coffee table, dining room
table, couch, love seat, lamps, entertainment center, washer & dryer,
I figure if its offered thats one thing but to ask is just wrong.
I just found a listing for a free 55 gallon tank though so I'm going to see if I can be 1st to grab it up.
