My site is stand alone

I'd certainly promote it with a decent return.

and one of the standards of economics *besides, buy low, sell high, make a profit*.. is:

It's always easier to Lower your price than it is to raise it.

and with your unique niche i do think you could command better pricing. Since you have a following already, maybe keep them as "gold" members and for the new ones coming from affiliates, have a better pricing.

Good Luck!!
