I think the Timbuk2 Dime Bag is a discontinued product, I could no longer find it on timbuk2.com. That explains why it is 50% off at Cineleisure’s Timbuk2 shop. The usual price was S$29, and now it is selling for 50% off (S$14.50). The only colors available are red and green.
Do note that the Timbuk2 shop at Cineleisure has moved from #02-03 to #02-10 (beside Xin Wang Hong Kong Café). The shop name has also been changed to Bratpack.
