A Flash Sale is a BRAND NEW item on SALE for 24 hours or until it sells out. These brand new items tend to sell out quickly so if you see a Flash Sale item, get it ASAP. Once we sell out (or 24 hours go by), it will go back to regular price when it comes back in stock. Sorry, no rainchecks. Please note: Flash Sale items are always on brand new items. Not old inventory.
