Shoppers picked up a range of bargains - most 20 per cent, 25 per cent and 30 per cent off - but some were even more.

Emily Hall, of Kings Meadows, said the best bargains she bought were cheap stationery at Birchalls and shoes at Red Herring.

Almost 90 stores, including cafes and restaurants, took part in the sale and new central business district retail stores Sportscraft and Wanted even got involved in the day's winter fashion parade.

Bras N Things was one of the new participants in this year's sale, and store manager Tam Robinson and assistant manager Candice Green got into the day's theme and dressed up as superheroes.

Birchalls operation manager Will Cassidy said this was one of the busiest Crazy Day Sales he had worked.

``We started getting set up at 8am and the first transaction went through at 8.40,'' he said.

Cityprom executive officer Vanessa Cahoon said she was thrilled with how the day went.

``There was a fantastic vibe in the city and there were a lot of staff dressed up,'' she said.

``From the feedback we've had, this is the biggest crowd we've had in a long time.''

Four Crazy Day shoppers were even lucky enough to win $250 shopping sprees.
