14X12 Promotion in annual product

[ferran.sitja@redcorus.com]

Hi everybody,

 

I have 2 products with different prices and plans (Annual and Monthly).

I'd like to offer a promotion via email campaign of 14x12 (2 free months extra) to the anual product for new clients.

 

What's the best way to do this? Can it be done with promo codes?

 

Thanks in advance!
