Last Boxing Day, millions of shoppers thronged Britain's high streets, spending almost £3bn. Many had queued overnight to be sure of snapping up a bargain.
While most of us won't go to those lengths, few can resist the sales altogether. But if you want the best buys, you'll need sharp wits and even sharper elbows - as well as a bit of a strategy.
There's something about all those big red 'sale' signs that seems to trigger a feeding frenzy amongst shoppers, and it's easy to come away with bagfuls of stuff that you don't really need or want. So start looking around the shops now and create a wish list, noting when each sale starts. (This isn't always possible, as some stores, such as Marks & Spencer, don't release their sales dates in advance, presumably to encourage us to buy more now.)
Most of us end up spending more on Christmas than we really intended to, and getting into debt is no way to kick off the new year.
"A good shopping plan starts with doing things in the proper order," says personal finance expert Erica Sandberg. "Budget should always come first, and paying bills should never be a struggle because you spent too much."
If you're shopping for clothes, make sure you know your measurements. And be selective: there's often a good reason this stuff hasn't sold before. Stick to timeless classics in good fabrics, designer items, bags and shoes. Knowing what you want is even more important when it comes to furniture - it's all too easy to impulse-buy a sofa that's too large for the room.
Sales items often get pretty harsh treatment, so check for lipstick marks and tears before you buy. If you do get home and find something's faulty, you'll be legally entitled to a refund of the amount you paid (despite the fact that some stores try to deny this). But if you just change your mind, it's a bit of a lottery: some stores will give you a refund or replacement, some won't.
If you want the best selection, of course, you'll need to hit the sales right at the beginning; prices often keep falling through January, though, so the best bargains come later on. Don't be seduced by big discounts alone: that £100 dress may have 60 percent off, but is it worth £40 to you?
Increasingly, shoppers are staying at home and doing their sales shopping online.
"The biggest shopping days of the year are the post-Christmas sales, both on and offline," says Andrew Walker, country manager of price comparison site PriceRunner. "For savvy shoppers, online shopping can make the sales stress free, avoiding the crowds and those regrettable impulse purchases."
For many of us, though, the lure of getting what we want right there and then outweighs such concerns. Braving the crowds can often be fun and, says Sandberg, is frequently the cheaper option.
"Online shopping is great for comparing prices, but traditional in-store shopping still has a lot to offer," she says. "There's something very festive about shopping in the store during the holidays. And these days, stores are working hard to combat the online shopping trend, so you may find your best deals inside the store."
Sale starts 26 December at 10.00am, running until 6:00pm on 19th January. Discounts often reach 75 percent. Last year, the sale was opened with a performance by Cirque du Soleil; no word yet on this year's celebrity.
Sale starts on 26 December, with discounts of up to 50 percent on designers including Marc Jacobs, Chloe, Paul Smith, Lanvin, Stella McCartney and Christopher Kane.

Sale starts 26 December. Up to 50 percent off some items, with discounts on womenswear, accessories, beauty, furniture, childrenswear, luggage and home accessories. "Some luxury items up for grabs last year included dresses by Stella MacCartney, Miu Miu jackets and Chloe and Marc bags, so fashionistas should get their credit cards at the ready for similarly stylish bargains this year," says the store.
Currys PC World
"All I can tell you is that the Currys PC World sale will begin on the evening of Christmas Eve," says the spokesman.
Sale starts 26 December, running until 2 February, and there's a pre-sale on furniture from 5 December. There's up to 50 percent off on selected furniture, lighting and home accessories. The Skanda Small Sofa, for example, is now half-price at £648.
