Wanting to buy new packs but not update game.

Hello everyone, I'm sorry if this is not the place to ask this question so I'll understand if it gets deleted.

Seeing as there have been many updates that have broken many mods, I've chosen to do the recommended thing and play offline for a while. However, I would also like to buy some new packs, as they're currently on sale. I'd like to ask if there's a way for me to do this without installing them yet? as it would probably also update my game, which is not something I'd like right now.

Again, sorry if this is not the right place and thanks in advance.
