Depending on the weight, UPS is sometimes cheaper. Once, I had a package go to Canada. I had to jump through hoops and give a credit card number for it to go UPS, which was at a customer's request. Long story short, the Canadian customs charged the person more than the item was worth in customs. They were going to charge our credit card, but the decent buyer paid it out of pocket instead of having us held up by Canadian Customs.
Now, we have a disclaimer that says item is described exactly on customs forms, exact value is stated, and whether it is a gift, merchandise, or whatever is stated, and that the buyer is responsible for whatever extortion and fees their country wants to charge.
