Grab bag Comics? Yes? No?

Do you guys remember the days when you had those mystery grab bag comics for like a $20 you could get 100 random comics and stuff.

I actually liked it. Yes you got some pretty crappy issues but the excitement of maybe finding 1 good key issue was great!

Plus it would be comics I'd like never pick up but were some good reading time. I think some stores should bring it back just for the heck of it.

I mean if you want to introduce someone into comics what not a better way?
