Dan here from the Guru team! Thanks for reaching out today through our forums. :) First off, I think you are on the right track and the site looks great! I love that it is really easy to navigate through, products are consistent in size, I would suggest having all your images consist with either a background or just a color background. :) I did notice you had a piece of coding showing up above the free shipping bar.
You can remove it through the html/css, theme.liquid file on line 9.
You can access it through your online store —> Themes —> … Edit HTML/CSS.
Once you remove it, you can see it will remove the space at the top of your free shipping bar
One other thing I would suggest would be adding a Product Review app to all your products so people can write a review, which should help with your SEO. :)
All in all, I think your site looks great!!
I hope this helps; and thanks again for posting. :)
