Op should get notification for deals getting marked as expired.

In my personal experience, most of the grocery deals are location specific. if a user alert admins that deal is expired so it's really hard for them as well to find out whether the deal is actually expired or not available for specific locations. In this case the deal gets updated as expired and OP doesn't get any notification for the same. I think if OP starts getting any intimation about the deal expiry then they can quickly check and update if it's still available or not. It's hard to keep on checking your deal in time to time to make sure it's still active.
