Meredith, I have no business sense whatsoever. But your jewellery is phenomenal. What might work in your favour as opposed to other vendors who have tried that location is that you can offer a wide diversity of product in terms of both design and price range. People may not be able to spend a lot right now in today's economic climate, but they still want to be able to buy. You offer beautiful jewellery at affordable prices - which is crucial when "affordable" means something different to every person. That might drive more people into your shop.
