I made a spreadsheet that calculates how much the products in the Premium Shop are worth.
From their $ cost vs the resulting "collapse piece" value you get from them.

There's even a Purchase Order if you just want to get the most rolls out of your cash.
Should give an idea which products you can buy first that will yield more rolls.
I also added some tips and and other useful notes for purchasing in general.
Note I am on sunborn server, and will only calculate in $.
