One thing I would add in general, is that many people are blissfully unaware of the fact that they could well incur customs/duty fees when their purchase arrives from another country. I would be quite clear in pointing out that the buyer is liable for these fees.
On a $2.99 toy it won't be a problem, but I do know people who have had quite serious problems with buyers who expect the seller to cover these fees...and they can be expensive!
