A few games in the winter I couldn't get to because of illness so used StubHub and it works fine. I can't afford to lose money but only want to cover my costs. Even with the StubHub add-on I don't think my ticket costs the buyer more than the matchday price ,say £40 ish in the MS. I think that's fair enough.
What I object to is tickets going on sale at £90 to £120 plus fees which are currently advertised for the Burnley game .It would be quite easy for Everton to clamp down on this. It wouldn't really affect StubHub ,they charge about £5 to both the buyer and seller which I think is reasonable.
