The other thing to consider is just how much food prices have gone up in the UK in the past couple of years. And wages generally have not. Its a general trend here and with things like gas prices having jumped some insane percentage (£200 a year more for our household) and fuel is average £1.35 a litre for our area, factor in other living costs and its not cheap to live here at all.
Food items are increased in price, not only a few pence but 20 or 30p a time. I know my food bill keeps creeping higher and higher. And the meal deal things like BOGOF don't really help as often they are for junk foods or processed foods and I don't like to use those too much.
A few things I've noticed while shopping of late that have increased
*Bread (named brand) - gone up from 70/80p a loaf to an average of £1.20
*Hummus - Jumped 20p
*Baby wipes - now almost double the price
*Tesco own brand tissues - a few months ago 25p a box, now jumped 20 pence or so
*Digestive biscuits (named brand) 79p now £1.09 (they cunningly snuck the price up after they were on special for a couple of weeks and people forget the price beforehand)
*Ready meals - Another trick they are doing here (hubby eats them sometimes and I do notice this happening as a wider thing) is to keep the price the same but reduce the weight by 25 or 50g or so. This is also being done for tinnned stuff, sauces, ketchups, cereals and so on. So you pay the same but get less weight wise.
*Chocolate - cocoa prices have gone through the roof due to shortages at source. So even a Mars bar costs the other side of 55p these days. A Twirl was recently 57p! Buttons are 55p.
Chicken has jumped a massive amount in price. Even a couple of fillets cost a fiver. You can't buy those mass produced water injected £3 chook deals in Tesco these days, thats for sure (actually glad as this was so bad for the farmers and the birds, never bought one).
Fish - Cod is very expensive. Its been overfished and is now therefore stupidly priced. I can buy salmon more cheaply and yet that is considered a 'luxury' type fish by many.
I know even when I am holidaying in Aus I don't compare prices. I guess my years of living overseas got me well used to not comparing. There isn't any point and even when on holiday, I figure I'm on holiday so I am not going to worry. Its not like we are splurging on fine dining every night we are out or anything. Just the usual stuff and we keep within our limits.
