Wrinkles anyone?

Mint color King size bed sheets by Martha Stewart amazing price at Costco. Excited got home unpackaged washed and dry just like package states, I stopped the dryer and pull it WRINKLY SHEETS! They look like they were dried in a ball wet!
They were soft to touch but not nice to look at. I still use them, made my bed thinking wrinkles would disappear after being places on the bed. Nope. Next day after sleeping on them still wrinkly. Soft yes.
Miss big time on quality of fabric.
