I've lost one of the rubber tips for my in-ear Anker earphones.  I called in to JB Hifi to see if they have replacement tips for sale, but apparently not.  A quick search of trademe found a few options, but in most cases the shipping cost is almost 10 times the item cost.  If I've got no other choice I will go down that route, but I figured I would ask in case someone here has some spare earphone tips lying around.

I think the ones that I've been using are x-large, though they might just be large.  If anyone has spare tips that they don't need and would be happy to pop them in an envelope, I'd be eternally grateful and more than happy to reimburse the postage costs.
