Walmart replaced my TPMS sensors--they had the best price (all 4 for $128), and since they also did the Goodyear Reliant tires for that car, did a rotation and balance at the same time. Went early in the day, got it out quick too. Don't know what TPMS brand they installed, but all have been working normally for about a year now.
All that said, our last tire purchase, for the wife's car (#1 ride) did NOT get foreign tires, instead got USA sourced Generals and road force balancing, at Discount Tire. Her wishes ruled, and to seal the deal Discount Tire had a pretty good deal with a pair of stacked General Tire rebates and price matching to Amazon who was running a 20% off sale.
