I’m new to shopping online at Kate Spade outlet and was wondering if items ever come back in stock or once it says it is sold out is it gone forever? I was debating if I should buy an item that was listed as new on the website and next thing I knew it was sold out. I don’t know if I should keep checking back to see if it comes back or if it’s a lost cause and to move on. Thank you for any insight!
