We do but not very often! Why? We are a platform where the creators are in control, if we ran site wide promotions every month we would devalue their offering and you wouldn't take us seriously.
Occasionally there may be a flash event, but you won't know about it until its launched, we see you sale campers!
Rest your laurels knowing that when you DO see a sitewide event, that it will be a very long time until we do another, so get grabbing!
Bare in mind, sale events are optional for creators and they have a right to opt-out. Some creators prefer to run their own sale events, so be sure to check back often, or, follow them for updates.
