I remember I got my C=64 from Children's Palace for $199.95. It came out at $600, I think and dropped to $400 soon after that. So $200 was a solid deal.
I ordered peripherals through the mail from the big mail order electronics vendors. I think it was J&R Music World.
I got a floppy drive, but the case was obviously cracked and a piece of plastic was missing.
I sent it back. I never got a replacement. I never got a printer. I did get the nice 1701 monitor.
