Fighting back against supermarkets

I did a quick experiment this weekend.
I used my local butchers (Sandersons in Baxenden, Lancs) as I do every weekend, weighed out all the meat and compared it to Asda on price.

The quality of the meat I get from the local butchers is far superior to that of a supermarket, time from supplier to counter is vastly lower at the butchers, the meat is bought locally, which keeps costs down, less emissions, etc. (The money generated also stays in the local area, as opposed to going to shareholders in far off lands)
But also my local butchers does not buy in bulk, so does not have the buying power, farm discounts, etc, of a supermarket. In theory, these should outweigh the extra storage, chiller, transportation costs easily.

* 3 prime fillet steaks
* A prime steak joint, which my butcher was about to cut 3 fillet steaks from.

Total weight: 1450g (1.45kg) of prime fillet steak - Asda price (£34 per KG or £3.40 per 100g) = £49.30

* 14 Pork and apple sausages

Closest available comparison at Asda was two 6 packs of pork and apple sausages - Asda price (For two 6 packs, 12 sausages at £2.50 a pack) = £5

* Lean braising steak (5 slices - I never buy the diced stuff)

Total weight: 950g of braising steak - Asda price (From the "Butchers counter" - which is misleading as it's the same meat off the shelf) is 97.5p per 100g = £9.26

* Streaky bacon

Total weight: 450g of streaky bacon - Asda price (79.2p per 100g) = £3.17

Total Asda price would have been £66.73
Total local butcher price was.... £35

"Saving you money everyday" say Asda.
Exactly how are they allowed to get away with these claims?

On meat, I've proved that shopping at your local butcher gets you higher quality, younger and fresher meat.
On price, my local butcher beats Asda by a country mile.

If you want genuine quality, permanently lower prices, better service, then shop local.
Can you afford not to?
