Kits returning to storefronts is probably the smartest decision the higher-ups have made in a while.
This was something I mentioned in my Marketplace feedback. I said I would reconsider purchasing kits if they returned to the EA App, where I have previously bought all of my Sims DLC from.
I'm relieved they actually listened. I'll now be able to pick up the last two kits that were released, as I didn't get the chance before the changes were made.
I'm very happy that all official DLC can be bought on storefronts again.
