Tokyo Groceries

How much are groceries in Tokyo? What kinds of food can you buy? Is meat expensive in Tokyo? Is "dollar store" food safe?

These grocery blogs come from a weird habit I have. It always starts as an attempt to decipher the Japanese grocery receipt, and then I start taking photos and geeking out. Normally, I decide no-one will care, then delete everything and try to move on with my life. But can I just indulge this OCD tendency and tell you about every single thing I bought at the grocery store today?
