It says "Have a shop that has made a total of more than 1,000,000sP! 0/1,000,000 " But I have made a lot more than that in my shop! For instance, I have the shop till saver achievement that says "Shop Till Saver Have 5,000,000sP in your shop till, at one time!" So am I missing something?

I believe you need to look at the 'Edit Shop' menu to see your total profits.

Whoo hoo! Yup, that did it! I just got 3 achievements instantly with that. Thank you so much! ^_^
