I'd say if $5/month + shipping is testing better, just make the checkout page say $5 + $5 shipping and maybe put the $5 shipping somewhere on the homepage as well in the description text.
Agreed. It just seems like you're pulling a fast one....as a potential customer all I really focus on is that dollar amount per month....I don't really factor shipping into the cost of your service.
Appreciate the feedback. Just had an internal discussion here and we all agreed that even though it may convert better, we don't want customers to have that feeling of shadiness when they get to the checkout page. We've changed it.
