You can transfer after the free one by paying a ‘single match’ fee, cost depends on the game category (£5 for a C cat up to £15 for A+)I believe a ST holder can transfer to an Albion + member once for free, if they want to transfer again the ST holder has to pay a one off fee of £20.
I honestly think more ST holders would be happy to transfer to a member if they didn’t have to pay the fee.
