The Project Pad

I'm trading Cabriolet tail lights with some folks in the UK - what's the most economical method to ship?

USPS. I have shipped quite a few things to Europe, and they always come up the best price.

USPS just had a big rate hike in the last few months, if it's a big box it will probably still be a lot cheaper than DHL (USPS just goes by weight, no dimensional pricing which DHL does and can be a killer) but small packages are really close in cost between the two now.
