I collect football shirts so I've got a lot, including every Spurs home shirt since 85.
I've tended to buy at least 2 of the kits each season to add to the collection, although I do often wait until they get into the sale, unless I really like the kit.
I've bought every Nike kit so far, aside from last season's yellow. I'd intended to at some point, but my enthusiasm for anything Spurs as the season went on dwindled so much that I just couldn't be arsed.
I'll pick up the new home shirt at some stage I guess, but will probably do what I did last year and take my pick from the other two further down the line.
If I didn't already have a collection that I feel some sort of ridiculous obligation to keep going, I doubt I'd buy any
