The shop has had a lot of success with its $1 sales, which help to clear excess stock and give the community access to good quality items at next to no cost.

Mayor Bobby Bourke, who is heavily involved in the running of the op shop, said the final sale of the year will be held on Saturday from 8am to 2pm.

A range of items will be available, including Christmas decorations, toys, clothing, ornaments, books, CDs and DVDs.

Cr Bourke said the flash sales have all gone very well since their introduction.

"They're on par with each other, we get around that $800 to $900 mark out of all of them," he said.

"One doesn't seem any better than the other. I hope the Christmas one is a bit better, as there'll be a lot of Christmas decorations, giveaways for the kids."

The money made from the sales is put back into the community, either by paying bills to keep the shop open so it can support people doing it tough, or into donations to community groups.

"I just gave $200 last week to a childcare centre to promote Christmas, and the food van is still operating; it costs us each week to do that," Cr Bourke said as an example.

Saturday's $1 sale will be held on the op shop's lawn.

Items in that vicinity will cost $1, while items inside the op shop will remain at their usual prices.
