CMLR, I feel like you missed the key point of Chaos0xomega's post.
You don't need friends in other countries. Parcel forwarders are companies that exist in places like the USA and the UK
that allow you to buy product online with a US or UK
shipping address. Basically, you pay them a fee, they give you a mailbox. Then you buy all the toys you want and get them shipped to that mailbox. When you're ready, they'll box all the product up and mail it out to you.
The problem is that you may end up getting hit with customs/taxes and import duties. However, the likelihood is that even including these, and adding the cost of shipping, if you buy enough product from discount retailers you will still save money over your local prices. Unless you live in Brazil - Brazil's import taxes are insane (like 100% of the value and up kind of insane).
Yet again, nope. Between they asking for a comission and my national mail service, I do end up paying absurdly high prices. Maybe not as laughably high as Brasil's, but I have ended up paying for my toy soldiers pretty much the same price again no matter how if it is not legally crossing the border by your own (and sadly I'm not overexagerating it on my particular case).
