Nancy wrote We hand make our products and there can only be one of any given item. After a product is sold. I would like to be able to leave a product up for viewing, but make it so that it can not be purchased. ...... Can you tell me if/how to do this?

It's easy to achieve this.

1. Unselect Disable Inventory checkbox and choose Checkout Completed for Reserve Stock mode at Settings > Inventory
2. On Product Inventory screen, enable inventory for the product, increase stock from 0 to 1,  choose  Show  As  No Stock  (Don't Allow Purchase) for out ot stock mode.

we'll add an Email This button on product detail screen in the future, so customers can email the page to store  or  their friends.

We'll investigate this.
