A Martin Lewis fan has explained how she saved £288 on their car insurance with a quick five-minute check.
The MoneySavingExpert reader, known only as Sarah, was quoted £650 for her annual car insurance renewal.
But after using the MSE car insurance tool, she was able to knock this down to £361.08 - a saving of £288.92.
She said: "I was really happy to be quoted £361.08 for comprehensive cover, including breakdown, with my partner as a named driver.
“With the cost of living going through the roof, I really appreciate the input from everyone at MSE."
A car insurance comparison website will check the prices of dozens of different provides to give you the best quotes.
You'll normally need to enter your number plate and details about yourself and your driving history to bring up the best price.
MoneySavingExpert has previously revealed the cheapest day to check for car insurance quotes.
Looking for prices exactly 23 days before your current policy runs out could see you cut your price in half.

Of course, the amount you could save does depend on your individual circumstances and if you have made any claims in the last year.
MSE analysed more than 70 million quotes from comparison sites to find this optimum time.
The consumer champion website also noted how it is also still similarly cheap a few days either side of this 23-day mark.
But leaving it to the last minute could end up costing you hundreds of pounds more, as insurers are more likely to view you as higher risk.
Not all car insurance providers are listed on comparison websites - one of the biggest ones being Direct Line - so always check directly with companies as well when looking for quotes.
Car insurance is one of the biggest outgoings for drivers, so it is always worth comparing prices when your renewal date is approaching.
You could also try haggling your existing provider down in price.
Haggling is by no means guaranteed to lower the cost of your bills, but it doesn't cost a penny to ask for a better deal.
The first step is to compare prices. Once you’ve found a better deal, call up your current provider, tell them about the cheaper price you’ve seen and ask if they can match it.
If they can’t, and you’re not fussed about moving to another provider, you may be able to switch penalty-free if you’re not tied into a contract.
