I just went through this process on the same tires earlier this month. One big factor on some online tire dealers is shipping, then you need a local shop to do the installation.
I found a local shop that sold them for $285 each and mounting and balancing was an additional $18 per wheel. You might check independant shops as your Goodyear, NTB, Tires Plus type dealers may have limited inventory options.
I had a pair of TA/KO's that were take offs in okay shape and my dealer accepted those in trade for the mount & balance.
By the way, the Toyo M/T's are an excellent choice, quiet on the highway, excellent performance and aggressive looks. We've had a few good slick ice/snow events this month and I've been unstoppable
