Our shopping cart is currently being upgraded. The new version should be a little faster and have a few more features. In the meantime, the site will remain closed. This process will probably take a few more weeks. This is the first time since the web site was built three years ago that we've had to be closed for maintenance. I would rather do all the maintenance at once with the site closed, than have shopping interrupted again later on in the year. Thank you all for your patience.
