The iRobot Braava Jet 240 is retailing for S$469 but during IT Show 2017, the price drops to S$399.
John Ackerman, who is the official distributor of iRobot products in Singapore has a booth at IT Show 2017. At the booth, they only accept Cash or NETS payment only. I ended up getting my Braava Jet 240 from their website as the discounted price is applicable online as well. Delivery is fixed price at S$18, or you can pick it up from their office at, Blk 34 Upper Cross Street #04-138 Singapore 050034.
