I know this is one that gets mentioned now and again, when i first joined there was a 10% discount from some vendors, to me this seemed to be a deal maker for a lot of people. I'm not complaining about it being gone myself but if there was an obvious benefit i think more people would pay their membership.
Maybe a one off dicount voucher from a willing vendor for 2 yrs + membership that way it would be worth it when people want bigger tackle items,
this is a loose idea i know there'd be a lot of if,whens and but's, maybe theres a good workable varition to this.
