Singaporeans are not online grocery shopping people.
I'm not sure about that - if you call any of the online delivery places in the run up to Chinese New Year, you'd be lucky to get a slot within 2 weeks.
Latest from NTUC (Fairprice) - they're hopeless. Twice in the past 2 months I've put an order in only for them to call me and ask if they could deliver it in 2 or 3 days because the stock wasn't due in until then. Yet if you go in to any of their shops they'll have all the things you need right there (just not the delivery service for you to be able to buy it there and then and have it delivered to you!).
So they either need to sort their warehouse out so that their online service runs more efficiently or they need to start offering free delivery (if you spend over a certain amount) from their own stores, because their online shop is useless.
I've spoken to them in the past about this but they just fobbed me off with excuses
