Vending machines are not that popular than in the Japan but it’s still popular and have more variety than here in Malaysia. I saw that the vending machines in Guangzhou do sell comdoms. Great, a way to promote safe sex. LOL
By the way, I saw these vending machines at the Guangzhou Metro underground station. In my 2 cents, it’s faster to go to the nearest 7 ELEVEN, then pressing on button.
