Our store www.ayurmeans.com is designed with 'Flow' theme. It is a good theme but very few Apps work with this theme.
I am looking to add 2 features to our store with coding.
One - Sticky call to action buttons for mobile device customers. (Using an app for this feature 'Sticky Add to cart Booster Pro'. It is slowing the website I guess)
Two - In-cart upsell like showing shipping message 'you are x away from free shipping' or showing some related products on discount to add in the cart itself. (Need urgent help here)
Hope to get help from someone on this.

There are more amazing things in it I would suggest you to check...!!!
You can try out HypeCart which is great for upsells and cross sells both in the cart and after the checkout. If it doesn't work with your theme, just let us know through the app and we'll sort it for you!
