@jkg-jkg,
Some of those bookies you listed have some pretty good offers:
Quinnbet - injury time insurance on selected football match odds, refund if 2nd to SP favourite, BOG after 12pm time.
Blacktype: enhanced Specials, weekly casino stake 20 for 10 spins, weekly free bet club.
10bet: 2nd to SP favourite, price boosts.
Betsid: price boosts, in-play football offers.
MansionBet: small free bet reloads on Yourbet I think it's called, casino free spins reloads, price boost.
All are good without being spectacular for value.
