This is a targeted offer; it seems only people who received the email can register, but some people who didn’t receive the email were also able to sign up, so it’s worth a try. HT: WeChat reader Fang Jie

If you’re able to register successfully, don’t forget TCB also has another $15-$5 offer (expires 02/23), so you can stack it to make a perfect $15-$15 deal.
