I recently sent out an email to my customers with both the name of the discount and gave them a link to the site with the code built in as a cookie.
Several results.
One is that they are able to use it both ways! When entering the site the prices show the discount properly but if they enter it again at checkout another discount is given!
I thought it could only be used once.
The other problem is that the code is not sensitive to capitalization. i.e. december and December are both valid.
How can I offer a decent email without this happening. Only use one or the other?
There is no warning in the guides or FAQ's that this can happen. Is it a bug?
