Designer puppies?

Ok, when I was growing up these mixes were just considered mutts and were way cheaper than the purebred dogs but anymore they cost as much as an akc reg. breed. We were doing some puppy shopping today at Arky Barky in Sherwood today and I had major sticker shock. $799 for a cock-a-poo!!!!!!!!!!!! That is insane!! He was a beautiful dog and had a very good personality, but $799??
