Tell me, why should anyone believe you if you're wearing their signature and posting about their services. I mean you're a walking advert for them, even your 2 last posts are praising them in 2 different threads. Is this your way to say "thank you" or are you on a payroll?
GM is a ripoff and 3% discount won't change anything. You'd need to be offering at least 20% to give people a chance at earning anything with them.
