@GGG should I wait?

I have 440 microtransaction points and I want to get as many stash tabs as I can. I recall hearing that you guys intend to implement "packs" though after open beta, to "pass on the savings" to us. Can you elaborate? Will I be able to buy a huge pack of stash tabs and come out a ahead? Or can I go nuts now and not worry?

I'm obviously not a GGG member but it has been stated quite a lot of times that they do not exactly know what is going to be purchasable in the shop and to which prices things going to be sold, so you might not get an answer at this point.
