mail box rental

Does anyone have any experiences with mailbox rental/package receiving type places in PH? I know theres the place on the Slope side of Flatbush, and another place (I think) near Beast, but I've never used one of these services before, so I figured it can't hurt to ask.

I don't have any experience with them in PH but in general in NYC, it is much, much cheaper to go to the post office than to one of the mailboxes etc. places. I was quoted $30/month for personal use, $40/month for business from a mailboxes etc. and they had a 3 month minimum. At the post office it was $58/year. For the post office you may need to put in an application and wait a month or so if they are all full but it really didn't take too long for me.
