variable product expiration dates
I teach classes in my store. I want to set up a product that is my class and variations for each time it is offered, so all people have to do is select the date they want from the drop down, but I want to have the variations removed after the class has started. Right now I have to do this manually which is very time consuming and makes my site look out of date very easily if I don't have time to remove it immediately.
There could be lots of applications for this. A special variation of the product only available for a limited time ect.
Maybe one of those might help you
