Islanders can get free advice from around 20 consumer-focused organisations to celebrate 30 years of the Jersey Consumer Council.
The two-day event, which is the first of its kind in Jersey, will be held at the Town Hall in St Helier next month.
It will bring together a wide variety of local groups under one roof, so people can get a range of advice - from the cost of living crisis to online safety - and tips on how to cut their grocery and energy bills.
Carl Walker, Chair of the Consumer Council, says this made more sense to mark the JCC's 30th anniversary this way, rather than with a black-tie event or a fancy celebration.
"We thought 'no, let's actually do something that helps consumers', (and) pack the Town Hall with as many people as want to come along.
"It's a free event where people can come and receive confidential advice, but also get some great tips on how to save money, how to budget, and how to get the most out of life so that they are not struggling as much as they might be.
"We're quite certain that everyone will leave that building with at least one thing to take forward and share with their family and friends."
People can pop down to the fair on 19 and 20 September from 9:30 am until 4:30 pm.
There will also be a series of free talks on Friday and Saturday.
Groups taking part will include Trading Standards, Citizens Advice, Enable Jersey, Highlands College, the Jersey Office of the Information Commissioner, LibertyBus, Jersey Fire and Rescue, and the Jersey Competition and Regulatory Authority, among many others.
