EasySell COD Form & Upsells

I am using this app from few month and I am happy with the app functions,specially their WhatsApp support . whenever issue comes I message them and within 6-12 hours it got solved, very quick action by their developers,As per my request Now discount code is also working for draft orders as well,Now my store sales has increased 5 times after using easy sell form, because this form makes customer to place order easy whereas standard checkout system is quite difficult for those customer who is not familiar about it.
Happy User
