Don't waste your time going to this location. I brought in a box that was perfectly fine to ship - no rips, holes, or dents and completely sealed. They refused to accept it, saying it wasn't up to their standards. They then tried to sell me a new box for $9! Um no thanks, I can get a box for 1/3 of that price at OfficeMax.
I took the same box to PostNet (an authorized FedEx provider) and it was accepted without issue.
