The boxes of parts in the promotion don't seem to have a help file on how exactly to use them. I know I'm missing something painfully obvious but...
1) How does one use it if setting it up and can it be replenished during its short duration of being up?
2) How do you actually shop from them? Someone had one set up before and I couldn't figure out how to pay it to get an item from it.
Again, don't judge, I know I'm missing something obvious! :P
