Which? has accused manufacturers including Apple, Google and Amazon of charging way over the odds for tablets with higher memory capacities.
Amazon has defended the use of a swear-word on a Christmas card as “light-hearted.”
A clothing company has apologised for selling T-shirts with the slogan 'Keep Calm And Rape' - claiming it was a mistake.
Rarely has there been such a dramatic example of a sign of the times. Jeff Bezos, not so very long ago the founder of an internet start up company, has bought the Washington Post, one of the United States' most respected newspapers.
What is more he has paid the $250 million out of his personal fortune.
What beckons now could be a massive shake-up of the American newspaper industry which has been suffering as ad revenues and circulations fall. And as our newspaper industry struggles too it's worth remembering where America goes the UK often follows.
Amazon boss Jeffrey Bezos is to buy the Washington Post newspaper for a reported $250 million.
In a lead article on the newspaper's website Bezos is quoted as saying: "This will be uncharted terrain and it will require experimentation."
The sale will end the Graham family’s stewardship of the paper after 80 years and four generations.
Bezos founded Amazon nearly twenty years ago, when he was 30 with a $300,000 loan from his parents, and started working from the garage.
Online retailer Amazon today told customers they will have to spend a minimum of £10 to qualify for the site's "Free Super Saver Delivery" option.
The limit applies to all products except books, DVDs (including Blu-ray), music, video games and computer software.
In a statement sent to customers, Amazon said the the change - effective from today - "will affect only a very small proportion of orders".
However, numerous departments such as electronics, clothes, DIY, health, beauty, sports and jewellery will be affected.
Online retailer Amazon has stepped up the battle for music sales with the announcement that it will give away digital versions when customers buy CDs and vinyl records - and they will backdate for any past purchases.
The free MP3 service, named AutoRip, will enable Amazon customers to have instant access to music they have bought days before their purchases arrive in the post.
The firm has already lined up in excess of 350,000 albums for AutoRip with more titles to be added, and said there will be no knock-on effect on its prices.
Tracks will be added to customers' Amazon Cloud Player account and can either be streamed or downloaded to devices such as iPhones, iPads, Kindles and smartphones.

It's an absolute disgrace that Amazon is paying such tiny amounts in tax.
The Government should be clamping down on tax avoidance rather than slashing the welfare state, privatising the NHS and cutting legal aid for ordinary people.
This shows us yet again that the Government is making a political choice rather than an economic necessity.
- Amazon's main UK subsidiary paid just £3.2m in tax last year, according to official accounts, despite overall UK sales of £4.2bn.
- Amazon's taxes for last year are only marginally higher than the £2.5m the company received in government grants during the year.
- The company's tax bill was £1.9m in 2011, but these sums may not actually be paid to HMRC because of cumulative losses across the Amazon group.
- Amazon employed 4,191 people at the end of 2012 in the UK but reduced payments to the British government by routing sales via a subsidiary in Luxembourg.
- The UK company declared a turnover of £320m for 2012, up 50% on 2011.
- However, its income is largely raised from other Amazon companies in return for services such as warehousing and distribution and negotiating purchasing deals with book publishers.
Today's scheduled Google grilling comes as the chairwoman of the committee, Margaret Hodge, revealed that Amazon also faced being hauled back to explain its financial dealings.
A Guardian investigation claimed its company filings showed its main UK company paid £3.2 million in corporation tax on sales of £320 million last year while the Seattle-based group told investors its 2012 UK sales were £4.2 billion.
Mrs Hodge told the Guardian:
My committee has real concerns about the extent to which companies like Amazon are stretching the rules in order to avoid paying their fair share in tax.
By any measure of common sense Amazon appears to have a proper established presence in the UK, and that there is a discrepancy between some of the evidence in this report about its activities in the UK and what the committee was told by Amazon when they appeared before us last year.
We will now consider whether we need to recall them to explain that discrepancy.
A report last December by the committee accused both companies, along with Starbucks, of "immorally" minimising their UK tax bills.
Michael Fowler, founder of US clothing company Solid Gold Bomb has apologised for the offensive slogans on T-shirts advertised for sale on Amazon.
In a statement on the company's website, he said: "I am sorry. As the party responsible within our company for scripting and creating this automated process that created the matched slogans for this "Keep Calm" series, I apologise for the offensive response this has created across the world".
He went on: "Currently, our listings have been fully removed and we are working to delete the entire parody series.
"Rest assured, we do not condone the offence nor do we have any desire to promote it."
The offensive T-shirts available for sale on Amazon which said "Keep Calm and Rape Her" are unlikely to exist away from the internet, an experienced web commentator has told ITV News.
Blogger Pete Ashton said the company Solid Gold Bomb has more than 500,000 different products for sale on Amazon, which would suggest it is using a computer programme to generate the designs for the T-shirts. Once a design has been purchased the company then makes the T-shirt, he said.
Mr Ashton, who is not connected to the company in any way, said the use of computer algorithms to develop designs online is common among web retailers, blogging:

Yes, Amazon shouldn’t be advertising these shirts. Yes, Solid Gold Bomb should have checked through their verb list before starting the algorithm. But as mistakes go it’s a fairly excusable one, assuming they now act on it.
