I'll see what I can do. When I was over there last weekend, they had quite a few in the bin. However, the first time I found it and bought it, I went back exactly one week later to grab one for a friend out west and not only were they all gone, but the bin was half empty (this was back in early January). I kinda figured it was the price and not the fact that Port Huron, Michigan is crawling with Mute Witness fans. Nonetheless, it's a vastly underappreciated film and it's director, Anthony Waller, has yet to top himself.
I'm going over on Friday, so if I spot copies, I get you one.
I really wish Wal-Mart Canada would start doing this. Our under $5 discs are almost always that public domain crap. $6.88 sometimes gets you some decent catalogue stuff, but only at Boxing Week or for about two weeks in spring/summer when they have another "blowout," and even then, they're selling some titles for $11.66 and $14.66 and $17.66 that ALL goes in the US bins at $5.50. WE ARE GETTING RIPPED OFF UP HERE!! And at a store, no less, that seems (at least locally anyways) to be the paragon of quality for every piece of trailer trash we've got 'round these parts (perhaps yours has a little more class).
For a good deal, though, no amount of fat pants and hair dye can stand between me and the bin!

Anyways, I'll keep you posted on Mute Witness.
