Discount retailer Aldi has beaten the "big four" to be named best supermarket at the annual Which? awards.
The consumer watchdog said Aldi took the title "for its impressive range of best buys, quality food and good pricing", trumping competition from major players such as Sainsbury's, Tesco, Asda and Morrisons.
It follows Kantar figures released on Tuesday showing that Aldi seized a record market share of 3.6% in the 12 weeks to June 9.
Aldi UK's joint group managing directors Matthew Barnes and Roman Heini said: "Being awarded Which? best supermarket is a real reflection of Aldi's success in 2013.
"Winning this award for the second year in a row just goes to show that consumers in the UK are moving away from the big four supermarkets, realising that swapping to Aldi can save them a significant amount of money on their weekly shop, without having to compromise on quality."
Other winners at the ceremony were John Lewis, named best retailer, Bosch, who took the best home appliance brand title, and Samsung, who won the best computing brand award.
Skoda won best car manufacturer and Tesco Mobile took the title of best telecom services provider, while Amazon won the award for best customer care.
The Which? local business of the year award went to The Hampstead and Highgate Heating and Plumbing Co based at Enfield, Middlesex, while the Good Food Guide Readers' Restaurant of the Year was named as Delifonseca, Liverpool.
Which? chief executive Peter Vicary-Smith said: "In these tough economic times it's fantastic that there are companies who still go the extra mile for their customers to provide good quality service and value for money products.
"Being recognised by Which? is not just a mark of excellence, it can boost business. Research shows approval from Which? can influence people's purchasing decisions and a third of people who've seen one of our endorsements say it might even make them increase how much they are prepared to spend."
Seven of the craziest supermarket glitches
Aldi wins best supermarket award
One of the most popular glitches, was a wine deal at Tesco back in November 2012, where a series of offers clashed, leaving a bottle of £9.99 wine selling for £1.50.
The 'three wines for £10' deal apparently clashed with a '25% off when you buy six or more bottles' deal. The 25% was accidentally taken off the original price rather than the reduced one, leaving the wine at rock bottom prices. Deal-hunters cleared the shelves around the country.
Perhaps the most popular glitch from Tesco came in June 2011, when instead of taking £4 off the cost of a £20 case of beer, the supermarket accidentally started selling the cases for £4. The ensuring rush was nicknamed the 'beer stampede'.
Sadly not every supermarket pricing glitch comes with such a happy ending for consumers. In March last year the bargain-hunters thought their luck was in, when Tesco accidentally priced the new iPad at just £44.99 instead of around £650. Sadly it spotted the mistake before shipping the goods. The small print on its website meant it could refuse to sell at this price, and refund their customers instead.
In September 2012, Asda was responsible for one of the most expensive glitches. The Asda Price Guarantee offered vouchers to customers who could have got their shopping cheaper elsewhere.
However, when certain trigger products were in the basket, the supermarket massively under-priced the shopping at other supermarkets, and offered huge vouchers to shoppers. In many instances the vouchers came to roughly the same as the cost of the shopping.
In April, a mistake on their website resulted in Tesco selling 8 packs of Bulmers cider 568ml bottles for £5 - rather than a six pack for £8.
Deal-hunters snapped up the deal online, and had varying degrees of success. Some had their order delivered in full, others had six delivered for £5 - and were able to negotiate their way to another two, while others were offered six for £5 or their money back.
October last year saw one of the most famous glitches, when Tesco Terry's Chocolate Oranges were subject to two deals at the same time, and the price dropped from £2.75 to 29p. There were plenty of people getting chocolate oranges last Christmas.
A buy-one-get-one-free deal went awry at Tesco in March. People putting four tubs of I can't Believe It's Not Butter or Oykos yogurt packs into the trolley were only being charged for one.
Soon the online deal-hunting community was in action, with one person bagging 50 tubs of butter and 22 pots of yogurt for £8.79 - a saving of £133.89.
