Why does the lumia 720 cost more than 820, 920?

On eBay the 720 goes for more than the 810/820 and sometimes more than the 920. Why is that?

I'm not entirely sure why, but if I had to guess I'd say its because of the unibody design that features MicroSD support, which the 920 doesn't have and the 820 isn't unibody. It also has pretty high specs for its place in the range - to the point where some people favour it over the 820. Add to this the fact that it seems to be a bit more of an elusive handset - I know here in the UK you can only get the 720 from one place on contract, otherwise you have to buy it outright from somewhere like Clove or Expansys. I think it might be the same in other places. Great phone but not a lot of carriers seem to carry it and I can't quite figure out why!

it's a more beautiful phone and does everything 820/920 can do(well, almost)
