THAT'S WHEN YOU'RE WRONG!
That same uncle,he had a branch shop at Orchard too.Wheelock Place,which is walkable from Ion,has a place that Uncle Ng owns too.
It's called Dollz Inc and holds stocks of toku toys as well.Usually it's more expensive by A LOT,like 20 bucks more or even higher because of the rent in Orchard.However,that store's main focus are dolls which uncle's wife likes.
When Chinatown do not have stock for something,you might be able to see it at Orchard,but it's definitely more expensive.
I bought an IXA with stand for $60 there but that's because Chinatown didn't have it anymore.The branch at wheelock place have vintage mechas too but likewise it's expensive too.
