Offerly: Make An Offer Button!

We operate an online retial store in combination with a Marketplace. I came across this app and it seemed to offer the option enabling a potential customer to make an offer for a product. Critical is that I can select certain products or groups - Offerly does exactly that. Offerly has nice customization options such as popup on exit - or inactive time. The app is atable and I'm looking forward to more customer interactions. Although I've set it to auto accept or auto decline -which doesn't leave any additional work for me.
