Just my 2p's worth, but the membership fee is a steel, 28p per week for info/knowledge, deals, events and banter that you just dont get if you buy a tabloid once a week!
Look at it like this, a Haynes manual is circa £20, it is never updated and there is no 24/7 customer support service or an index page full of banter, photos of drunken antics, a page full of vouchers, an events calender, Tom Tom icons, help with ICE/IT/tuning/styling/home entertainment....
The guys that run this place do so in their own free time and it does not go un-noticed, be patient, the stickers, along with the rest of the club pack will arrive in due course.
