The discount will only be 10% or so anyway. Not exactly major discount. Even GSF do this on their slim margins.

I always ask companies for a 10% discount on prices anyway, and with a competitive market place, if someone else sells the same products, you can usually get it.

But you will still make money with a 10% discount so i really cant see how it makes any difference to you if the person asking is a member, a non member or from mars. You still make money and lose the same amount on the discount. :D
