I got burned once with customs to Canada. I sold a dragon statue to someone on ebay for $50, then insured it for the said value (just in case), and when it hit customs they charged her $50...the value I had put on it which she already paid! Customs can charge whatever they feel is right for a duty fee apparently. In the end I gave her back all her money so as not to get a bad rating on ebay so I lost out. The customer was furious but at least she didn't have to spend the duty fee.
Now, every time I ship parsel post to anywhere around the world, or buy anything from around the world, I never insure it and ask that they do not. It's a big risk, but I've been lucky. I also do allow for tracking and signature delivery which I find prevents thefts and such. I mark everything as a gift with a value of less than $10USD even if the product cost $100. I've never had a problem with customs since, but again this is a risk. A high-priced item like the Pleo RB...I don't even want to THINK about the duty fees and hope they go easy on you. Sometimes the item description itself can determine what they will charge you, it seems. I always make the contents sound truly boring when I ship, however accurate, just so they don't think it's some expensive thing they can dip into other people's pockets for.
