I believe I saw someone with an achievement for having acertain amounts of sP in their shop til, but when I look at the achievements list I don't see it there.

Is there a certain link to it? Does anyone know what the amounts of sP are to earn the achievements?

It's under 'basic' on your achievement list. There's Shop Till Saver (have a certain amount in your shop till) and Making a Living (have a shop that has made a certain amount of sP over time).

You can find it yourself if you look under the 'basic' category, but the amounts for Shop Till Saver are 100k, 500k, 1m, 5m, 10m, 50m, 75m, 100m, 250m.

Thank you!!
