Christmas alcohol sales pricing
An email popped up from Saimsbury's about the great savings they're offering for lager and cider; hmmm cider okay I'll bite and take a look.
This cider is reduced in price; this you can buy two of for this price; this you can buy three of for this price and this comes in three different sizes with different prices. So yeah easy to sort out or at least it would be if they displayed the saving and the price per litre. Beyond the extra information why would this be useful?
Consider the Stella Artois offers at the bottom of the page. Buy one 568ml bottle for £1.61 instead of £2.15 they even state it's 25% off. However I could buy eight 568ml for £10 instead of £11.95. Which is the better deal?
1.61/2.15=0.75 That is £1.61 is 75% of £2.15 and therefore is a 25% (1-0.75) saving just as they say.
10/11.98=0.83 That is £10 is 83% of £11.98 and therefore is a 17% (1-0.83) saving.
The single bottle is the largest percentage difference and therefore the better deal... or is it. How much do I actually get?
568ml = 0.568 litres 1.61/0.568 = 2.83. Therefore for the single bottle I would be paying £2.83 per litre. For the eight bottles that would be 10/(0.568*8) = 2.20 or £2.20 per litre.
So despite the single bottle offering the greater percentage off the eight bottle set is the better deal as a price per litre which is really the important thing. The full results are as follows:

Biggest 'bang for your buck' Magners Irish or Pear eight-packs.

Now you need to include relative alcohol by volume and then we'll really have "bang for buck".
Ta da! Gosh I wonder if there's a reason that the ABV values aren't displayed except on the main product description?
Still Magners Irish or Pear eight packs; but look at the Aspall - £151.85 per litre of actual alcohol!
Also worth pointing out the massive difference between the single of Stella Artois compared to the eight pack.
