Thanks for all the advice,
It seems there are a few options for me that I hadn't thought of. Basically, if the sales page is good I can use it and just create a squeeze page. Or if I don't like the sales page I can create my own. Or use blogs or squidoo etc to promote.
Hope i've got that right. Which method might depend on the actual product.
Anyway you've given me something to work with.
Sandy.
