A Dagashi

I bought a ”駄菓子” yesterday afternoon.  (I think "some" is better than "a", why does 駄菓子 have 駄の漢字？ it sounds like they are candies that are bought in bulk?  You wouldn't happen to have a picture would you?)
The ”駄菓子” is/are? very cheap.
And there are various kinds.
I want to boughtbuy a lot of ”駄菓子”. (Or, if for some reason this was the case: "I want to have bought a lot of 駄菓子 before tomorrow." Maybe there are no more available after tomorrow.)
Because I am an adult, I am buying them in a mood like a billionaire.(Better is "I'm buying them like I'm rich" or "I'm buying them like there's no tomorrow" or "I'm buying them like they're going out of style". "like there's no tomorrow" and "like they're going out of style" are set phrases.)
Today I'll buy a lot of ”駄菓子” on my way back home.
