Deceptive pricing – Multiplication Math Flashcards Review

Liked the app enough to purchase the full version for $2.99... but according to my account, it was $19.10. Wouldn’t say it’s enough to sue, but I’m not happy with my purchase. Makes me wonder if these other start-ups overcharge and just assume the customer isn’t checking.
