There are still some sites left for businesses and organisations at this year's Lawrence Lions Club's McKeown Farmarama.
Event organiser Dave Robertson said exhibitors should book as soon as possible for the agricultural showcase, which attracted big numbers of farmers, many of whom were hoping to spend on bargains.
Farmers also often bought product weeks later based on what they had seen at Farmarama, he said.
Farmarama, which has been held every two years since 1994, is a showcase for agricultural vehicles, equipment, services and sundry supplies and consumables.
The event will be held at the Lawrence gymkhana grounds on Thursday, February 28 and Friday, March 1.
