How do I increase the vending slots?

[Karrotz]

Is that only with sparkcash items?

I've upgraded to the red mini house and I assume the regen time is faster but other than that I see no difference. Is it worth upgrading at all?

Yep, this is a purely cash shop item.

And sure, if you have the money, a better mushroom is worth it.

Thanks. =)

Which cash item would that be? I seem to only find the mini houses with different looks.

[MineralAccident]

I believe it comes with the storage pack, not sure if you can get it separately yet.

Other mushrooms make you regen faster?

Yeah I only know of Storage Pack so far.

[Karrotz]

Apparently they do help you regen faster.

Ouch! The storage pack is expensive. =_=

Thanks all for the info.
