Never checked the standard thread as allot of what I use tend to be Acme thread. But thanks for the information.
Must admit I have never drooled but have brought through them before. TBH if their price isn't right then I think Phils price won't be either. Remember for the IAP GB they are getting it at cost and discounted price and supplying it to you with no profit.
I'm sure Phill won't be able to offer an "at cost service" 
But if Phill can get a good discounted price then it will be a good move to UK customers..
