I am getting my TE37 19s in a month or so, and I am doing some research on tires right now! I am probably going with SO3s. Please let me know, thanks!

So far, Tire Rack is the cheapest I can find!

 

TireRack is probably the best you can do unless someone has a "friend" at another retail store.

 

What I've done is to get a price quote from TireRack, then go to Tires Plus and get a quote from them. The TireRack's price will most likely be a lot cheaper than Tires Plus. But the cool thing is that Tires Plus will price match, and they have local stores nearby (in the form of Wheelworks/Tires Plus). Since they are local, you can get the tires installed immediately, rather than having to wait for the tires to arrive from TireRack. Give it a try!
