Currency is tricky. Using "$" directly here is not i18n friendly.

Not sure what is the best way to get this. We have CurrencyFormatter [1] that
can do this. But I am not sure whether it is okay to have deps on it but you can
see how to use ICU to format currency.

I confirmed with the @hejq. The price should be formated string with currency
symbol. It seems that I don't need to worry about this. Thanks.

Get rid of "*". Think it should be displayed via an image resource.

I am confirming with UX designer about this. In the specs, the star seems to
have font which seems to indicate a text, but I am not sure.
