Query: Rip-off Alert!!! Bought them for $245, now they are $345!!!

The Mirrors work great (altho hard to install), but the last two times I bought them on Amazon, I paid $245, now they are $345!!! What a Rip-off!!! Don't buy them until the price comes back down. They are just some plastic and a piece of glass. $350 for plastic and glass is outrageous.
