Dr. Diffs shipping cost.

I ordered an $3.00 "O" ring and it cost me $6.00 to ship. An envelope and a stamp would of worked fine. I guess it costs $5.50 to handle the "O" ring.
Maybe some are charging handling fees but all I know is, I mailed a check thru USPS, priority mail. 27 bucks. **** ain’t cheap these days folks. You all need to maybe focus on the cause of all this. I’ll give you a hint, it all starts in a limestone building.
