NoHo Pack N Ship has serviced the area for two years. It sells boxes, and within those boxes you can put items to ship with UPS or FedEx. If you have a move planned, the shop sells packing supplies along with the boxes.
It's also a handy place to make copies, both of paperwork and keys. You can also get gift cards, office supplies, stamps and even a couple of trinkets for the kids. If you want a secure place to get your mail, it has mailboxes for rent. This is also an authorized agent for Western Union money wiring.
