Here's what I recommend/noticed:
On the homepage don't just have all that text, but display your products also. Perhaps have the most popular one or the one in season stand out most. Have a call to action on your homepage that lead the user to do something. Right now the home page doesn't really do anything for the user.
Do you ship your product in jars? Show the finals images of your product and if you still want you can then display the fruit next to it. For example, take a look at Smuckers http://www.smuckers.com/products/ I understand that you're probably thinking that you're just a home based business, but presentation is everything and I'm sure you can achieve it.
Products: If something is not in season, don't display it on the site or least don't have it as the very first item.
Blog: Your blog looks so very different from your website. Keep it consistent! Also, I've noticed that when you click on the homepage link from your site, it takes you to a different home page (the one that doesn't have the blog link highlighted) http://jumpinjellies.com/?page_id=17
Plus, your blog doesn't have a link back to your main site nor any images to steer up that appetite for your readers.
Nutrition page: There's no way of getting back to the homepage and buying the products.
Oh and yes the shipping charge is crazy, there's no way I would pay $21.95 for a $6 product.
Hope this helps,
