posting a parcel price to Canada for Christmas

If you scroll down to the bottom here, you'll see the rates for "Rest of World". You can get a padded envelope in the Post Office for a small charge, depending on what size you need, and it can be sent as a packet (much cheaper than a parcel) if it weighs up to two kilos.

I sent a package to Florida last week full of crisps, chocolate and a few small bits and pieces for about 13 euro, including the envelope. Get posting as quick as you can tho, the guaranteed date for arrival before Christmas was last week as far as I know!
