I stopped using PP when they cut back on offering BOG for most meetings. Lo and behold, I get offered BOG on all UK and Irish racing. No idea how many get it.
Now in the habit of using B365 generally.
PP offers can be good; eg money back on 2,3,4 - but usually at poorer prices. I often use instead of each-way.
I understand overdoing use of offers is a good way to get shut-down.
