I believe that they now default to 2nd class post, which has caused some people to complain about postage speed. The forum has a big argument about their '24-hour shipping' promise - GS say that means 'end of next day', even if that's more than 24 hours away....
And there are continuing complaints about lack of stock, and their limited returns policy - though those have always been issues for some people. Has anyone got any recent news about the rumored new HobbyKing warehouse near Ipswich?
