Martin Lewis is set to return to ITV tonight with the latest series of his money saving show.
Joined by Angellica Bell, the financial expert will explain how you could be missing out on thousands of pounds.
He explains why this is the case, and more importantly, how consumers can get their funds back.
He also demonstrates how to make huge savings while out shopping, even when there is no sale on.
But many of the tips expected to feature in tonight's show are already out there in the form of Martin's own Money Saving Expert blog, here are some of our favourites:
Hidden discount codes
According to intel from shop workers , stores will 'pencil-in' codes on products which are to be reduced in upcoming sales - usually within a week of the markings appearing.
Typical codes at Next include B14, P7 or S13 - the letter is believed to relate to the area of the store the product will be moved to for the sale, but the number is generally the price the item will be reduced to. Clever!
Amazon free delivery hack
Did you know that there is a handy site out there which helps you find low-priced 'filler items' to reach the £20 free-delivery basket total?
The Super Saver Delivery website lets you type in the amount you need to add to your basket to qualify for free delivery, and suggests items you could pick up at that price to do just that.
For example, if you're 85p short of the total, the tool suggests picking up this Bostik Blu Tack - which can always come in handy around the house anyway - and save you a few quid in delivery charges.
Ditch your online shopping baskets - you could get a discount!
If you fail to complete your online order, companies will often send out discount codes in a bid to tempt to you to the site to complete your purchase.
While never guaranteed, it is worth a try if you're able to wait a day or two to see if they send you a voucher.

Buy gift cards for up to 25% off
Sellers at Zeek can flog unwanted gift cards at a discount of up to 25% off. Money Saving Expert advises that, as gift cards count as cash, you can usually combine them with sales or codes for effectively a double discount.
John Lewis refund tip
This plays on John Lewis's 'never knowingly undersold' slogan - but what you might not know is that it applies up to 28 days after you've made the purchase.
If you can bring proof of where you've seen an item cheaper - for example a print out from a website, or a screen grab on your phone - the store will refund you the difference.
There's even a dedicated form on the John Lewis website to process refunds and price matching for purchases made online.
The Martin Lewis Money Show is on ITV tonight (Monday, November 27), from 8pm until 8.30pm.
