Went to Wal-Mart. They didn't have them. They didn't even know what they are!

Looking at this and happyfunny...(lookds like an alias) other posting, seems to be FOB.

They're called 耳塞 and as the OP found out, you just have to try a few pharmacies as they're not very popular here, but most people will know what you're talking about.

is a pretty good deal, 10rmb for 12pairs with free shipping.

@Geogramatt you don't necessarily need a e-banking USB stick to use taobao. You can open a bank account to connect directly as well as a few other options (going to a convenience store to top up your account, or getting a friend with alipay to wire you some, etc).

@blueice
You mention going into a convenience store to 'top up your account'. Can you give some more information please?
What is this, what account?

NB I have ceased being amazed at the things that Carrefour and Walmart (especially) don't stock.

When I went back to Canada 18 months ago I bought a number of items not available here. Every one of them was "Made in China"!

@tigertiger

something similar to going to the post office:

except you can use lakala from the convenience store.

Excellent link, thanks.

Editor,
I wonder is someone would like to write a Dummies Guide to shopping on TaoBao. With and Without credit/debit cards.
