Yes it's fairly recent, still free with no MOQ for business accounts. To be honest I was surprised they had it at all.
FYI there are a few ebay sellers who make a business out of this - they have accounts with RS and Farnell that give free shipping, and when you buy from them they order the stuff delivered directly to you. Surprised me the first time it happened, I'd ordered some component from a UK ebayer and it turned up direct from RS.
