Online sales term meaning SIGN UP SALE. Its a term used when a specific product is being manufactured at specific time (usually a new products first release/debut) and the maker only wants to make the exact about to be purchased without having any overstock or extras after their sold. So a SIGN UP SALE we usually be posted or a specific, limited amount of time. During that time, anybody that wants to purchase the product will "Sign Up" my leaving a comment or message regarding that post so they will be guaranteed that product once it is made and ready to sell. Anyone else who didnt "Sign Up" during the time of the sale is basically just shit out of luck until the next time its available...
My new product is finally ready to be made. I only have limited materials though so there will be an SUS posted on the website until 5 pm on Friday. If you miss that then you're going to have to wait until the official product launch in October.
