Full-time national servicemen (NSFs) in need of ziplock bags, batteries, powder, socks, insect repellent, and even singlets and shorts, can now find them in LifestyleMart Express vending machines at White Sands Shopping Mall, where many NSFs gather before they return to camp, Lianhe Zaobao reported. ST Logistics, which runs army supply store LifestyleMart, announced the installation of the machines on its Facebook page last December.
