Well, some are sold. Check Peking.
anybody else with a more serious answer?
I LOLed. He's funneh.
What I can give you is to go to
www.taobao.com (China's largest online marketplace, more confusing but lots more stuff than eBay) and type in whatever you want.
Check their shopnames and see whether they have a brick and mortar store, maybe locate it and maybe buy from there?
I only know the few Taiwanese online retailers that have a storefront but not so for China. You might wanna ask one of our forum members, "pang0011" for details though. He seems to deal alot through China and he might give a heads up on where to buy in China.
PS: China's big. You need to specify where your parents are headed.
