To boost sales of e-cigarettes on his website, Boo Yee Fong held a lucky draw - the more you spent, the more chances you had to win.
He had bought his supplies from vendors overseas and made a profit of about $12,000 before he was busted by the Health Sciences Authority (HSA). The 32-year-old was fined $64,500 in 2014, the largest fine meted out to an e-cigarette peddler to date. The HSA also shut down his website.
Since 2012, the HSA has prosecuted 14 peddlers for the illegal sale of vaporisers such as e-cigarettes. They sold their wares on social media and other websites for between $15 and $198.
One peddler helped his friend set up another website to sell e-cigarettes, even though he had been caught once for the same offence.
Francis Chue aided Zhang Zhaoming to set up a website to market his products. Both men, in their 30s, had obtained supplies from vendors in Thailand and the United States. E-cigarettes worth about $20,000 were seized from them.
Chue was fined $16,000, and Zhang, $15,000 in 2015. The HSA has shut down both websites.
In 2015, the HSA also raided a peddler's Bukit Panjang flat and found he had sold about $100,000 worth of e-cigarettes.
The 31-year-old bought his supplies from various overseas suppliers. He also assembled and modified various e-cigarette products to sell them online.
The HSA has shut down his website but the case is still pending prosecution.
Members of the public who have information on the illegal sale of e-cigarettes can call the HSA's Tobacco Regulation Branch on 6684-2036 or 6684-2037 during office hours on weekdays.
