I have tried different promotional sites for my GDI but all they did was to ask big amount of money. I've tried the spider, but I was saddened when I saw that I have to pay more than $300 for their full support and I still have to pay for yahoo and google for the advertising.
I've discovered new ways to promote GDI, it's like when you join in here, you won't pay anything; the site will give you $125 sign-up bonus and you can claim it when your commission raise to $200.
They will advertise your GDI for 30 days for free! and, you can cancel anytime you want for any reasons, and no penny will be charged to you. http://www.wonderfullife.ws/tissa.htm
And another one, here, you don't have to pay anything cuz it's like an exchange site, when you register there they will promote you twice whenever you promote the site. It's all for free.
