EL SEMBRADOR review for Simple Bundles & Kits

I like this app, is good, the support is good, and I have 2 comments. 1.- Support only work via email, I would like this to be also via chat. 2.- Simple Bundles app, I would like it to have discounts for each product and that this also have a start date and end date of the package since these are temporary and have a lifetime. Thank you
