I can fit 5 – 5000m spools in a Small Express Parcel Post Satchel, 8 into a Medium Express Parcel Post Satchel or 12 into a Large Express Parcel Post Satchel. Once my current bags are used I will need to change some of my current postal rates. Since the savings on using snail mail are only $3-$4, I know I want my threads yesterday so use Express Post.
