@craigj1303 Sorry for the late reply, had a busy afternoon but I hadn't forgotten!
Firstly, I will edit the permissions so you can edit your own posts, as I wasn't aware you couldnt.
Regarding these offers, I agree they aren't perfect for matched betting.
I like the old fashioned bet and get offers, as you know you are getting the funds in your account.
If you back a heavy favourite (under 1.7 odds), then yes, when they go 2-0 up the lock in will be just above the QL's for the offer. Not worth it, in this case you are best suited to wait and see if it goes to 2-1.
However, when there is no clear favourite, it can be very profitable. Tonight for example, my close friend was on Tottenham & Shakhtar, he has made £750 tonight from a total of £1000 bet stakes. This is very tidy! Unfortunately I have been too busy to get involved.
It doesn't have to be too time consuming though, if you dedicate 15 mins to placing your bets and then use an App for Live Scores updates, it will let you know when you need to log in to perform a cash out!
It's definitely different to the old school Bet & Get offers, which were definitely a lot easier.
