When I stumble across something that I want to buy, or that sounds interesting, I stuff it there for later either A) 'Oh yeah, I wanted to get that' or B) 'people complain they never know what to get me'. I also so far have, two years in a row, managed to mention this in my livejournal 2 months before my birthday. ;)
I'll keep it in mind, though I really do want a copy of the other for the archive (though on reflection, it's scary how much my 13 year old self liked that movie...). It is obtainable on VHS, but what's the point?
