OBERON Business and Tourism Association president and Buy Local Oberon 2019 campaign committee member Helen Lowe says they now have 46 businesses on board.
"And it's slowly increasing every week and it's still not too late to join in," she said.
"Business owners only have to drop in and see me at HE Lowe Accountants in Ross Street and I can set them up with their vouchers, posters and simple instructions.
"We're still looking for more tradies to join in."
The Buy Local Oberon 2019 campaign has $5500 in shop local vouchers as prizes up for grabs.
Mrs Lowe said since the shop local vouchers began, they have generated spending of $484,700 in the town.
"This is money staying in town," she said.
The Buy Local Oberon prizes will be drawn on Friday, December 13.
