Hi

I have a seen a few Zen Cart sites that allow users to simply go to the store's website, enter their order ID and email address used in the order, and find the full details / invoice / comments of their order.

Is there a downloadable plugin for this, or is it a custom plugin?

If you are wondering, this feature is useful for customers who checkout as guests - meaning they can't sign into the store to track the status of their order, since they don't have an account.

All help appreciated

Thanks
S
