Replying to They sold me used skis?

I went to a ski sale today and bought some 06 t halls for $300. So i get home and take a closer look at them and there are a couple cracks in the edges and some rust as well. They place said they were brand new and everything, but i dont understand why there would be 2 cracks and rust on the edges...

Should i take them back and hope o find a better deal, or does it really matter that theres rust on the edges and a couple cracks when they said they were new.
