how often will new items be added to the store?

I have about all i need from the trooper badges at the moment and I am wondering if I should just stack them up (is there a limit?) or should i just buy skill shards and souls each week? What do you guys do?

I pretty much just hoard them at this point, hoping for new items to be added to the Store.

I buy trooper soul shards each week. Most weeks I'll buy skill shards. If I know an event is coming of some sort, I'll buy souls.

Otherwise I hoard them up so I can spurge on a new purchase or for something specific.

Yeah trooper souls as the trooper FC is so important for me atm. Same skill shards. I tend to get the rare souls too as there will inevitably be another rare soul even coming along soon.

Cheers,
Kim
