Really, and then pay shipping? Priority for that is $13, then even if he charged you $5, to save $3 or $4. That's crazy and you know how I love to save a buck. You might also want to check with USPS to see if that is legit to ship since it is pressurized. Could you imagine the plunger breaking off and filling a van with white dust, LOL the Feds would be all over that.
