We are planning to improve the layout of E-junkie Shop pages on our site in the near future, so they will become mobile-responsive; unfortunately, that layout isn't something sellers have direct control over.
If you have a Web site of your own, you would have full control over the layout of your own pages, and you can simply copy the Cart or Buy Now button codes we provide in Seller Admin and paste those into your site to sell your products directly from there.
