The reason they are limiting your is likely due to price differences in different app regions. Adding $80 USD (or CAD or whatever) and then going to a region with significantly lower pricing will give you a lot more value and be possibly illegal (the legality of the grey market is up in question, if not just frowned upon). They aren't enabling people to do this.
And, like JAG87 said, VLC isn't on the US or Canadian app store anyway. There are some VLC utilities, but not the actual VLC player.
