Thanks for the heads up. I just ordered a couple of Michelin A1 Airstop 52mm valve tubes for $15.50 (incl. tax) on Amazon, with $1 credit toward a future digital order (e.g., Kindle book) for choosing no rush shipping.

On September 28, 2018, I paid $29 for 4 (also on Amazon but third party seller), of which I only used 2 last month when I installed new tires.
