Surely pre-launches give us affiliates another angle to come from when promoting a product?
I look at the overall launch schedule, the type of product and the 'fit' with my list.
Sometimes I heavily promote the pre-launch then go a little lighter on the main one, or the other way round.
Sometimes I won't go near a pre-launch because it feels like it's been 'tacked on' as an afterthought.
Personally I think all launches are different and you have to go at them from different angles, ALWAYS with your list in mind. What suits my subscribers might not suit another persons list and the pre-launch gives me thaht extra angle to come from when promoting.
Love em! ;D
