You pay $2.00 to go into the store. They consider it a donation.
They you can take whatever you want. For free. They stamp your hand
in case you take your stuff out to your car and want to come back
in. That way you do not have to pay another $2.00 to go in. If you
can not afford the fee to go in, many times someone else will pay
it for you. Or the store will just let them in.
There are other thrift stores that just charge for each item you
buy. Not the two I go to though. They are closes to me and I go
quite often. They sell clothing, housewares, furniture, music,
books, etc. Lots of things. I always donate my stuff there since
they are so generous.
