Affiliate Marketing Secrets

I’ve been looking at this beanie for a little bit now, and I really want it: http://us.asos.com/countryid/2/ASOS-Rib-…
But one thing I’ve been debating about whether I should really buy it or not… is it worth the money or is it a waste of money?
It’s still slightly chilly in my area, but it’ll be warmer anytime now. So then should I just save it for when fall comes? But then ASOS would probably stop selling it by then… it’ll be “out of season.” So I should probably prepare for the cold, right? We always have crazy weather over here, sometimes it’s raining, sometimes it’s snowing….
Anyway, the main point is, is it too expensive or not? And why?
