Brake booster boot

I've been searching high and low for the boot that goes over the rod that goes thru the firewall. I only found MP Brakes that sells one...

I figure well, I'm up against it so ok, filling out the order form and bammo!!! They want $23.69 to send a $29.95 part!!! I cancelled the order for now. There gotta be a better way to not get HOSED on what we know ain't gonna be more than $7 - $9 shipping! I really need it but damn!
