Is it possible to reduce the prices?

No, Creative Market recently introduced an inane Minimum Pricing update (following a price hike a couple years ago from 30% to 40% fees) -- their greed only grows. Unfortunately, I can't even link you to the article explaining the Minimum Pricing updates because their Help Center is completely broken because their team can't even implement Zendesk properly. Just avoid Creative Market & save yourself the headache...
