Thought this might be handy for someone in the UK :)
7dayshop is possibly the best UK supplier for Eneloop batteries (well, sort of UK because they are based in the Channel Islands). I use them often, in fact I had some AAA Eneloops arrive from them earlier in the week. IIRC they also ship to the EU.
Yep, over the passed few years, I have bought several lots of batteries, chargers and memory cards from 7dayshop, amongst a few other bits and pieces. Standard (free) postage generally takes a few days from Guernsey, but never had anything not arrive. Great return policy - any issues, they will resolve them for you. They now have a free post box for returns, so you don't even pay return shipping. I highly recommend them.
