Ms Nadia Ng, 34, pooled together some money with a group of fellow mothers to buy fleece jackets at sporting goods retailer Decathlon on Wednesday evening.
The mother-of-two told CNA she had seen videos online of children being pulled from the rubble in Turkiye.
“This is really nice and not unexpected to me. Singaporeans, they have really big hearts,” she said, gesturing to the stacks of supplies.
But for Mr Calvin Seah, the co-founder of The Black Hole Group, the outpouring of support was something out of the blue.
The 38-year-old said his firm had expected perhaps a table full of donations. But when they opened their space, it quickly became packed with people and cars. Staff members also stopped their work and helped to collect donations.
Police officers who turned up to manage the traffic situation also started to help carry things, Mr Seah added.
“This probably looks like a lot but it’s barely enough for the people (in Turkiye),” he said. “We’ve been getting calls from people asking how they can help, asking if they can volunteer, what time they can come over.”
