It has come to my attention that i am an idiot. I snagged a complete set of OEM Mazda TPMS(s?) for about $120.00. The guy at Town Fair Tire said he would install them for no extra charge when he put my snow tires on. Took the car in this morning at 10am, picked it up at about 3pm. As I unlocked the car and sat in my seat I noticed a box sitting on the front seat (lock nuts for oem rims). The box reminded me a lot of the box the TPMS(s) came in... which i then remembered was still sitting on the counter in my kitchen!
DAMNIT!
Fortunately for the guy realized I forgot them and offered to throw em on for free if i bring it back on a quiet day.
