New Post: How to customize DNN NB_store Checkout Module

Have a look at this page for information on adding custom fields to the checkout:
https://nbstore.codeplex.com/wikipage?title=Custom%20fields%20in%20the%20checkout

There is also some info at the bottom of this page on inserting a date picker - Some people have trouble with this, usually due to what jQuery code is included in their DNN and/or the store. You'll need to know how to deal with jQuery:

To get the custom field into a specific place you would need to modify the module.. probably checkout.ascx.
