Problem is I haven't yet been assigned a carrier so it might not be TNT and even if it was I don't have a carrier number to quote at them.
I think it may be the case that if you are only having stuff from China delivered you get TNT (or whatever) assigned from that point. Therefore you can track on their site and you don't feature on apecode.com. But because I've got some other stuff which is already waiting for me in Daventry, it's only there that I'll get TNT. In the meantime I have to use apecode.com which tracks Flextronics Logistics (I think.)
