chore: temporarily revert of price changes in #239 (#261)

Towards #254

We are cutting a set of contracts for the M3 milestone. The price
changes in #239 was done with
#250 being landed in
mind.

Since #250 is not going to land before in M4, I have temporarily
reverted the price changes, so that we keep the price intact for the M3
contract publishing.
