I'm looking for some advice, friends. █████ and I will be traveling in France and Italy this summer. We are reasonably experienced world travelers, which of course means we have a small collection of electrical power adapters and transformers. Our last overseas trip, though, was three years ago, and in the time since our fund of small devices has proliferated. Between us we now have two iPhones and two iPads. We plan to bring those with us this summer instead of bulkier laptops and piles of books.

Instead of relying for power on a bunch of big transformers, I figured that Apple would probably make travel adapters that would be easier to carry and safer to use. It turns out that, yes, they do make a World Travel Kit with replacement adapters to plug your USB cable into. Unfortunately, they only seem to sell them in sets of six—one each for region of the world.

I need four European adapters, but I don't want to spend $160 to buy four full kits. Does anyone know of an alternative whereby I can purchase only the adapters I need? I'd prefer to buy Apple products, but that's not an absolute requirement.
