Discounteo

Easy installation. Does not impede the speed of your site. Runs quietly in the background. Integrates with mailchimp without issue. Configuration - for a email marketing novice like me was a challenge, but once done, works exactly like it says it will. Appreciate the 50 free signups a month given I get like on average 3 or so a month right now :)

If looking for a straight forward discount app - especially for new email marketing signup prospects, this is one worth checking out.
