This front page story from the Daily Mail uses language which would not be out of place in a report about war crimes or serial killers. First of all, in the headline we have 'cut-throat'. Cutting someone's throat is a nasty way of killing, but here the expression 'cut-throat' is used metaphorically. If you describe a situation as 'cut-throat', you mean that the people involved are prepared to use every possible means to achieve success, even if it means harming each other. The expression 'cut-throat competition' is very common in the business world.
Above the headline we find a tagline with the phrase 'price-slashing frenzy' and the word 'battle'. This continues the idea of shopping as war. 'Slash' is a very graphic verb. If you slash something, you make a long, deep cut in it. However, 'slash' is also used figuratively to mean 'reduce by a large amount' (prices, for example).
The warfare analogy is continued in the article itself. Note the use of expressions like 'go head to head', 'savage', 'price war' and 'guerrilla sales'.
