Deezer (deezer.com) is a relatively new online music service. I tried the free trial and liked it. I was going to sign up for a paid account until I googled it, and found out that it's £4.99/£9.99 in the UK (similar to others, I gather), but $4.99/$9.99 in Canada and the US (Canadian or US$), and a little less in Euros (3.99/8.99). This is blatantly overcharging us for the same exact service; we just pay 50-60% more (or whatever) depending on the exchange rates!
I suggest we write to them and complain (I've done so). You can too at support.deezer.com/. The cost of living here is bad enough with this kind of thing added in just because no one complains, so they can. If other services are doing the same (haven't checked up on spotify, the main competitor), we should complain there too, and boycott them too.
