Couldn't go past that after seeing this nice proof:
Miningrigrental prices of cheapest rigs - prices going from
0.0111 BTC/GH/Day and up.

NiceHash price for renting 200 TH/s in fixed order (that means guaranteed speed, no need to worry about bidding) - only
0.0106 BTC/GH/Day.
So, tell me, am I crazy or are these people who still rent from much more expensive site?
