Last year, one in four of us bought something in the Black Friday sales, but of those, one in five said they regretted their Black Friday purchase.
The most common reasons given for regretting Black Friday purchases in the survey of 2,000 people in January 2020 were that it was an impulse buy (45%) and that they had spent too much over the Black Friday period (34%).
Fortunately, most retailers extend their return windows over the Black Friday and Christmas shopping period, giving you more time to return any presents or purchases you’re unsure about.
Some retailers, though, offer more generous returns policies than others, so it’s well worth double-checking returns deadlines if you know you might want to take something back.
Expert advice: Black Friday advice, insider tips and tricks, plus what deals are really worth your money
Here, Which? looks at the biggest high street retailers’ Black Friday and Christmas returns windows, and shares tips for taking back unwanted purchases and gifts.
Which retailers have the most generous policies?

Amazon, Smyths Toys and Tesco have extra-generous policies, allowing you to make returns up until 31 January 2021.
John Lewis & Partners’ policy is similar, with a 28 January 2021 returns deadline for products bought between 8 October and 24 December 2020.
Boots also has a 31 January 2021 deadline for items with a gift receipt, but is only offering an exchange or credit to your Boots Gift Card.
Other retailers we looked at have generous returns windows all year round.
Lakeland has a three-year guarantee on all its products, while online sports retailer Wiggle’s returns window is 365 days and B&Q’s is 135 days.
WH Smith has also permanently extended its returns window to three months in response to the pandemic.
Richer Sounds, although its return window is only 28 days, told Which? that it looks at customers’ returns on an individual basis and will ‘bend over backwards to be understanding’.

Currys PC World, M&S and Waitrose want speedier post-Christmas returns

If you buy from other retailers, you might need to make a speedy post-Christmas trip to the Post Office or in store, if and when the high street reopens.
Waitrose hasn’t extended its window at all, only allowing customers 35 days from the date of purchase to make returns, which means you’ll need to buy gifts after 20 November to be able to return it after Christmas Day.
Marks & Spencer also has a short returns window, asking customers to make returns by 10 January 2021 for purchases made from 4 October.
And if you’ve shopped with Currys PC World, you have until 14 January to return anything bought since the Black Friday weekend.
Currys PC World says its returns period gives customers good time to return unwanted gifts and will review its policy if the current lockdown is extended.
Although Aldi, The Body Shop and Waterstones offer a generous 60-day window, you’ll need to make returns early into the new year for any presents purchased around early November.

Tips for returning unwanted purchases and gifts
1. Make sure you have proof of purchase
If you’re making a return, you’ll usually need proof of purchase – such as a receipt or gift receipt – to get a replacement or refund.
In lieu of a gift receipt, you’ll probably need to ask whoever sent you the present for their receipt or confirmation email.
Check the date on the receipt or email to ensure you don’t miss the deadline for making returns.
2. Check the T&Cs for unwanted vouchers
If you wish to exchange an unwanted voucher, you’ll need to check the T&Cs.
It’s unlikely that you’ll be able to exchange an unwanted voucher for cash.
You might have more luck in being able to change a voucher from an experience-dedicated website than with a gift card for a specific retailer.
3. Don’t accept credit notes for online purchases if returned within 14 days
The retailer’s returns policy might state that you’ll only receive a credit note or vouchers, but this can only apply if you’ve change your mind or have bought the wrong colour or size, etc.
The exception is for most items bought at a distance (eg online or mail order) where the Consumer Contracts Regulations give you a cancellation period that starts the moment you place your order and ends 14 days from the day you receive your goods.
If there’s a problem with your item (for example it’s faulty or not as described), you’re also entitled to a cash refund rather than a credit note or voucher.
