how common are wal-marts over there? Here in the US we have site to store, so you can order it online for less than $10US and pick it up at the store without paying for shipping. Or a lot of stores have it in stock here, maybe there.
I think Asda are something to do with Wal-Mart but not sure if they are anything like the US stores.
I got mine through Amazon as well (from the amazon market place) and I made my DVD player multi region by finding the unlocking code on the internet. I don't think it has ever been released on Region 2.
