This is a good suggestion.. but i have known people who have offered this service before and ended up getting fed up...
They ended up being taken for granted. I myself use to be one of those who have contacts and try to help members get good pricing... until i get fed up. When it's a good deal.. there's no appreciation. But when something goes wrong.. fingers are pointing everywhere :)
Honestly... good pricing is given if some effort is being made to form a rapport with a seller.. instead of running around looking for the cheapest price and going to the cheapest to buy with no loyalty to any shop.
I get mine from 1 or 2 shops only and my prices are unbeatable...
Honestly... it's not selfish mentality... but rather people are sick and tired of being taken for granted for the services they offered... y would they wanna bother themselves when what's important is that they can get it cheap for themselves
Cheers!!!
