Her purchase? Tableware.
Store employees were informed of Kate's arrival around noon before she came in and shopped around the store, scooping up some platters with tropical birds on them.
One shop associate said she heard the Duchess bought them as gifts.
"She didn't look like the magazine pictures, you know, without her makeup or anything," said another associate, who declined to be identified. "She came in, shopped around, paid and left."
The oval serving dishes, which come decorated with either cockatoos or parrots, retail for about $48 each.
