For those worried about buying from China
or selling to China, here are a few words:
The postal service in China is quite reliable and relatively cheap.
I send all items by tracked airmail (ChinaPost).
However it can be quite slow, I have had several items take
over 3 months to get to me, but it is improving.
Average is 3 or 4 weeks.

   For those unfamiliar with me, I am originally from Oxfordshire,  
England but moved to Shanghai when I retired.

I am a member of the GBPS and the Mulready Yahoo Group
and I run the gb-precancels.org website which now also
covers telegraph stamps and telegram seals of the world.

I am selling off my more traditional stamps, so that I can
buy items that I am now interested in.

Postage only 25p on each additional purchase of same batch.

I try not to make mistakes, but I'm only human.
Returns are accepted if I do.
I prefer Paypal, but for anyone that cannot use Paypal,
I can accept Skrill or a transfer to my UK bank account.  
  This is a reasonable 1911 £1 green stamp (SG320) by Somerset House.

Centered a little low but reasonable perforations, just a few shortish at the top.

Small crayon mark, but a decent example.
