Anyone know about US (Buffalo) PO box or service

[alohamom]

If anyone knows info about this, it will be you guys, my fellow canuck Dis'ers!
I am looking at possibly renting a US post office box, or even better finding a one time or per use service. Does any one else here have one or use such a thing. My cousin told me he saw a service on line for a one time fee per shipment but he had not used it and I was a little leary of it. Any suggestions or info? Also, I am wondering about shipping to a buffalo hotel. I know you can ship to some hotels (for business) but what if I was staying overnight for pleasure with extended parking (we are in March with Staybridge). I guess I can call the hotel and ask but I was wondering if any of you had done this, or tried to. Any info is greatly appreciated!
