15 Euros (about US $17) for a 15,000-prim region on the hypergrid-enabled Swiss Grid. Gloebit payment, voice, and varregions.
If a user has more than one region then each additional region is just 5 Euros (US $5.60) per month.
To turn a region into a varregion, there’s an extra fee of 3 Euros to make it a two-by-two varegion, 8 Euros to make it a three-by-three varregion, and 15 Euros to make it a four-by-four varregion.
