While trying to return a purchase from the Kmart website, I first had to find a local UPS drop off location. A Google search lead me to Postal Depot, which, as I soon found out, is a drop off point for FedEx and USPS as well. The two women who were working there were very helpful. The store is stocked with boxes of all sizes and shapes, and the staff seems to be very knowledgeable about the best mailing service to use for every situation(I happened to overhear the conversation the customer who came in after I did and was trying to ship a laptop cross-country).
