Simple request, add a "Limited Availability" icon/flag/header that would display next to the title of topics with limited availability.
Prime example of a deal that could use this, one off store misprices like this:http://www.hotukdeals.com/deals/forza-horizon-xbox-one-24-99-instore-sainsbury-2081931
Second example: all the limited availability Tesco deals that get a bad rap but are always useful to keep an eye out for.
This tag could added either by the original deal poster, by a mod, or by several normal members clicking a button to indicate it's limited availablity
(Similar to the "spam/expiry" system currently works)
Please implement this to take away the frustration associated with these limited availability deals, without removing them from the site altogether.
