With Wednesday’s news that new Pokémon are coming to Pokémon Go, developer Niantic is making sure you won’t run out of space too soon.

The developer announced on Twitter Thursday a 50 percent limited time discount on Pokémon storage. From Feb. 16 - 28, a 50-Pokémon storage boost will only cost 100 PokéCoins, which is the same as $1 in real-world money. Users can upgrade from the base 250-Pokémon capacity to a limit of 1,000 Pokémon and also use real money for purchases via microtransactions.

The promotion comes as Niantic prepares for its most significant update to Pokémon Go in some time. Niantic confirmed Wednesday that more than 80 Gen 2 Pokémon will be available in the game this week.

The first part of the update rolled out to Google Android and Apple iOS users early Thursday. Bundled tweaks in this update include genders for Pokémon, updated catching menus that make using items easier and various user interface adjustments. The second half of the update, which will likely include the Gen 2 Pokémon, is expected to be available by the end of the week.

Niantic’s sale is also one of the more substantive promotions the developer has done for Pokémon Go in recent months. Typically, the developer has relied on seasonal promotions like its Valentine’s Day event or Christmas Event, where users saw rarer Pokémon or item boosts. But as Niantic plans to roll out the first of several major changes to the game this year, the move from incremental promotions to larger campaigns is reflective of the developer’s scope and goals for Pokémon Go and Pokémon Go users.
