So I've just gained this one:

Achievement Earned! Shop Till Saver Have 100,000,000sP in your shop till, at one time!

Question: What are the ones past this? Any higher? If so what are the levels?

Thanks.

You can find the tiers of this and other achievements in this thread: :) http://subeta.net/forums/view/577908
