Re: how often do expansion packs go on sale in sims 4?

@a_bbaba_cc, @PhoebeSayLol, @elulu8: You can look at the sales promotion history (for Origin and legitimate online digital resellers like the Humble Store) on IsThereAnyDeal to get an idea of when sales occur; sales promotions can vary by country.

If you sign into IsThereAnyDeal (you can create an ITAD account or sign in with an existing Steam account if you have one), you can also create a waiting list notification (by selecting "Wait for better price") for a game/DLC that triggers whenever the game/DLC is on sale or reaches a specified price or discount percentage.
