What's the deal with shipping?
 

I was getting info on getting some porting templates shiped to me and here it is:
Mazdatrix: USPS = $12
Racing Beat: USPS = $34
I'm not one to swear but WTF (What The Fudge).

The cost of the streetport templates (both intake and exhaust) are
Mazdatrix: $85
Racing Beat: $73

Total cost
Mazdatrix: $97
Racing Beat: 107

I heard Mazdatrix just resells Racing Beat's templates, True or False?
