Tire Dealer trying to sell me older tires, what do I do?

I ordered mine online through Simple Tire. I called, and discussed what to expect regarding tire age? They assured me that they direct ship from huge volume warehouses, and typically their tires are at most a few months old. I ordered Sumitomos. They were a bit over two month old, when they arrived. I also saved a ton of cash by having them direct shipped to a truck shop, and paying their installation fee. I literally paid less than half of what the local RV shop quoted to put Goodyear RV tires on.
