Some had also been hiring props, including gargoyles and gravestones, for home parties.
Business was always busy in the week leading up to Halloween and on the day, Ms Pilkington said, with custom this Halloween on a par with last year.

This year, staff had lollies and entertainment lined up and staff would also dress up for the occasion.
Looksharp Victoria Street store manager Jihee Jung said the most popular costume among women had been a "tutu witch" outfit, which came in three colours. A "bloody bunny" costume had also appealed to women this year.
A "bloody master" costume had been popular with men as well as black robes.
Boys were going for classic superhero Ironman and Spider-Man costumes. Ms Jung said superhero outfits were always popular among boys -- as were Darth Vader costumes and vampire outfits.
Girls were going for costumes based on characters Elsa and Anna from the movie Frozen. They were also choosing colourful witch costumes.
Ms Jung said business this Halloween was a bit quieter than last year, when Halloween fell on a Friday. She hoped to see a rush of last minute customers tomorrow.
Sarah Leaning of The Warehouse said unicorns, Star Wars and Minions had been the most popular costume choices at the store this year.
"We've also had some great feedback on our new ranges including giant baby faces, inflatable house decorations and onesies of course."
Driven by popularity in the United States, Halloween started to take off in New Zealand about three years ago and year on year appeared to be getting more popular for New Zealand families, said Ms Leaning.
"But it's not just kids who are getting in on the fun, we've seen a real mixture with Minions, mullets and vampire capes popular dress-up choices for adults.
"With both Halloween and the rugby happening over the weekend, there is sure to be a festive atmosphere throughout the country," she said.
Harley Quinn, the on-off comic book girlfriend of The Joker, is the most searched for Halloween costume in America, according to a new Google Trends feature called 'Frightgeist'. She features in the movie Suicide Squad, out next year.
Other costumes in the top 10 include Star Wars characters, pirates, Batman, Minnie Mouse, witches, and Minions.
Meanwhile, police are encouraging parents, caregivers and children to celebrate Halloween safely by following some simple safety tips.
Children going trick-or-treating should have an adult with them, should stay in well-lit areas and should never go into strangers' homes, they said.
It was important to only visit houses where they knew the residents and to be careful not to frighten elderly or vulnerable people.
Police said there was plenty of advice in its Halloween safety advice video available on the New Zealand police website. In it a group of Wellington school children shared their ideas for a spooky but safe and fun Halloween.
Householders could download and print posters from the police website to put up on a window or front door. The signs either read 'Trick or Treaters Welcome' or 'No Trick or Treaters Please'.
"And remember - you don't have to answer the door. If there are any problems or incidents outside your house and you are concerned, you can ring police for advice or assistance," police said.
