Hi,
I have set up a site with ecommerce for a small café (using a great Ember template - thanks, Medium Rare! 
) The café has a regular menu with a few varying ‘daily specials’ which are only available on given days.
It has occurred a few times that a visitor places such a ‘daily special’ item in their cart but doesn’t finish the order, then comes back a few days later, this item still hanging in their cart, and they happily order it, although it is not available on that day. I am applying the condition of availability in the menu, but don’t seem to have any way to ‘see’ what is in their cart already.
Would anyone have an idea how to double-check during the checkout process whether the items in the cart match certain criteria? Please?
Thank you!
