I'll ship worldwide. You only need to pack it and weigh it once to get an online quote. Then remember the dimensions and weight and use online USPS or Canada Post.
I have heard more then one member state gross inconsistencies between what the website quotes, and what the final price actually was (and I dont think this was limited to one specific carrier)
Of course the online qoute is always lower, and it doesn't have to happen more then once or twice to really screw up your profit
And let's be honest, a lot of what is sold on here isn't making a ton of profit anyway
