Hi Pam,
Your products are great and have a real quirky/Tatty Devine-esque feel to them. I think the immediate changes would be to use a cleaner logo and reduce the height of this, introduce a strong typeface/accent colour and add delivery incentives/promotions to encourage sales. I've just sent through a few more store suggestions. We'd be happy to help make these tweaks or re-design and build a new store for you.
Thanks!
