Businesses can totally announce merch sales through their BMF.io membership. It's actually a smart way to keep fans in the loop. Since your followers are already on the platform and interested in what you're doing, dropping updates about new merch or sales there just makes sense. You can post about launches, limited-time deals, or anything else you've got going on. BMF.io's setup makes it easy to share those updates and even push them to other platforms if you want.
