Folks looking to promote their next big block-party, wedding or musical shindig can now get in on Snapchat’s action with these new temporary geofilters for the popular photo-sharing service.

Called “On-Demand” geofilters, they’ll allow anyone, including local businesses, to create temporary location-based filters that will show up whenever other Snapchatters walk through the area defined when they’re created.

The bad news? The new feature will cost you $5 per filter to create.

Setting up a location-based reminder on the iPhone is fairly simple. Those lucky souls with an iPhone 4S can just ask Siri to do it for them, but – like the rest of us – they still need to have an address in a Contact entry on their iPhone to make it work properly. Aside from typing in address information into the Contacts app, there’s an even easier workaround, using the Maps app.
