It's the last chance for members of the public to legally buy fireworks until next October.
The Isle of Man brought in laws 20 years ago to restrict their sale outside specified times.
The Fireworks Act 2004 means retailers can only sell them to the public at the end of October and early November for Bonfire Night, and for a week running up to new Year's Eve.
It means shops will only have fireworks on sale for New Year celebrations until they close later.
