Novelettes and Omnibus

So i have uncovered 10 (yes that's right 10) Novelettes i wrote a few years ago... each of them is around 8000 words now my question is simply: Should i publish them all (E-book form) and put them at $0.99 giving the first one away for free so $8.91 worth of little reads and then also post an Omnibus of all of them together for like maybe $6.00 ? or should i just smoosh them all together and not worry about individual?

Thank you in Advance ~Tia
