In online marketplaces, sellers use MST to stand for "must see today." These sellers think you should check out their item ASAP, because it will sell quickly. (Or at least, that's what they want you to think.)
If you've bought into the seller's hype, you should message them about the item immediately. So what are you still doing here? Go get that deal!
