The USPS has a program to supply packaging materials for military family members and friends to send packages to troops overseas, sailors on ships, etc. If you call 1-800-610-8734 and select option #1, then #1 again, ask them for the “Military Pack”. They will send you 8 boxes, tape, packaging materials, and labels. They will also give you an ID number so if your supply runs low, you just call them and they will send you more supplies. The materials take about four to ten days to receive. Since most places charge you for the box, tape, filler, and labels, this service should help you save money as you send care packages to those who are serving our country overseas or on ships. The new flat rate boxes are only 8.10 to ship whatever you can fit in them.
