Read that post and it doesn't sound wasted at all. Good for you man. If you had that much fun, good for you.
I bought some and then realized that where we live sucks for lighting them off. We're on a corner with no back yard and our side yards don't have a good place so we were stuck out front and too many cars drive by. After a close call with morons in a car that stopped just feet from the fireworks that almost got hit with them I had to shut it down. I'm giving my stuff away to someone that wants to have fun farther back in the neighborhood.
Again, good for you. If you have the cash to spend and want to blow it out, do so and have a blast, literally and figuratively.
