I've noticed that sometimes older posts (usually for hunt prizes) sometimes reappear in the 'popular posts' list. (As I'm writing this, 2 November 2012, a post from last February is appearing in the top five.)
So if you see a nice prize or freebie I've blogged, to avoid disappointment, please check the date of the post.
With older posts, the hunt or offer is probably over (or the store might have moved etc).
But you never know, you might another great prize or gift!
That's all :) Good luck!
