How can I see my current SimPoints total?

I was gifted SimPoints by a friend, and I know I had a few in my account to start with but I can't figure out how to tell how many I have now. I've looked everywhere I can think of, but can't find it anywhere in the Store or under my account details. I attempted to buy something today and was told I didn't have enough, but it didn't tell me how much I was short either. So even if I wanted to buy more SimPoints I don't know how many to buy.
