I am replacing a couple tires within the next few days and I have a TPMS light, so I thought that I might as well replace the TPMS while I change the tires. Where are the best places to buy the TPMS for a 2012 Fusion? I looked at Oreilys and Advanced Autoparts but they don't have the OEM Motorcraft sensors. I see them for sale on Amazon and Ebay, but I am always leery about buying parts from those two sites.

I am getting the tires done at Walmart Tire center (trust me, only for the tires, I wouldn't dare go for anything else there) And they say that they have a "TPMS Service Pack" for 15 bucks. Does anyone have experience with this?

I'm gonna call the Ford dealer tomorrow to ask about how much the TPMSs cost and I'm also gonna call the Walmart center to verify what this "Service Pack" even is. 

Worst comes to worst I have to buy my own TPMSs and have to recallibrate them myself, I believe the tool is only 15 bucks on amazon so I'm not too worried about that.

Would just like any takes or thoughts on this, thanks.
