Comex, one of Singapore's biggest and oldest IT and consumer technology exhibitions, is here again.

The four-day event at Suntec Singapore (levels 3, 4 and 6) starts tomorrow and ends on Sunday. It is organised by Exhibits Inc, a Singapore Press Holdings (SPH) subsidiary.

As the show coincides with the school holidays and there are plenty of great bargains to be found, it is a good time to get your gadgets and gizmos.

For example, you can get a Gigabyte Sabre 15 gaming laptop (booth 8108) for $1,799 (usual price: $1,999), while Secretlab's Omega 2018 gaming chair (booth 6225) will be sold at $469 (usual price: $620).

There will be enticing purchase-with-purchase deals.

For instance, spend a minimum of $250 in a single receipt or up to three combined receipts and you can buy a Kaze fitness tracker and a pair of Curve True Wireless Fitness Earbuds for $99 (the usual retail prices of both gadgets add up to $258).

At the show, you can also exchange your old gadgets and gizmos for cash vouchers.

Bring your used laptops, LCD monitors, smartphones, tablets and desktop computers (except do-it-yourself PCs) to the trade-in counters at Halls 603 and 604 for assessment. You might get a trade-in offer you cannot refuse. For more details, go to digitalhospital.com. sg/comex2018-tradein.
