Surely any offer is only +EV relative to the odds available, no? You could have the best PP promo in the world (CS bets refunded if Barce win the CL final in 90 mins, for example) but if they're offering 3/1 on all scorelines then it's going to be -EV.
Similarly prima facie "poor offers" (CS refunded if Ashley Cole scores the first goal) are +EV if you can find a no-loss qualifier.
I guess it's up to blowingbubbles how he runs it though!
I have a bit of a predicament - I don't want to put a -EV offer however if just before KO it turns out to be a good offer and people missed it then that's not good either. I will try to use my best judgement but I'm welcome to any negative/positive feedback
I personally would prefer to see as many offers as possible -EV or +EV.
In my opinion, EVness is in the eye of the beholder on Sports Betting.
