Hello Heather,
While Marc takes a look into your site and products, here are a few things you may want to look into, as well.
Simple things may affect how your products are driving sales and traffic. Example would be the photos and description of your products. The more pictures, the more you can generate sales. Of course, the pictures need to be attractive and properly arranged with a detailed description. Customers like to read about products, too.
It's true that how they are priced compared to the actual ranges in the market affect sales. If they are a bit higher, then perhaps you can try offering shipping discounts and the like.
These may just be simple stuff to ponder on, but pretty true when you think about it.
What products have you sold out of your household items? You may want to rethink your niche if that would be the case.
