I really appreciate all that feedback and examples you gave me, I will implement those ideas asap. This is the first time I've ever created a website or designs, so extremely new to this and basically teaching myself how to do it, so your feedback is really appreciated!

I have implemented some of those suggestions, but unsure on how to do the following.

- add buy now button under the "add to cart button"

- Change the layout of/add things to the footer at the bottom of page.

- add refund and shipping policy to product page. 

Any guidance on this would be great! Could you also have a look at my website again and let me know about the changes I have made based on your feedback.

Thanks!
