You may want to consider ordering goods from Great Britain as soon as possible because the British Pound is near parity with the American Dollar and consequently more affordable to Canadians, as you can see from the current exchange rate shown in this graphic:

Alibris U.K, Amazon.co.uk, HMV.com and Musicroom.com are the U.K companies I import from the most and I tend to order CDs, sheet music and film on DVD/Blu-ray from them, the latter being playable only on multi region players, which can be purchased from Amazon Canada and Amazon America.

You should note that some DVD and blu-ray players can play Region 0 discs, some in PAL so consult your player’s manual for details.
