I had a package to send to my daughter. I could fit the potholders and a towel in the "all you can stuff in a box" box for $15.+. I got a regular paper box, stuffed the potholders and towel PLUS 3 more towels into that box. I went online to the USPS and calculated ------- that box was cheaper to send. Yes, it was not Priority -- but what I was sending wasn't "needed" right away. I actually saved something like $4.00. I always go online and figure out what it will cost for every scenario.
