Easy access savings accounts are not the only ways of saving - paying off / overpaying your mortgage, paying into your pension or opening up a stocks and shares ISA are all ways that should beat inflation over time. You also need to establish a safety net of savings to cover things like redundancy, the boiler breaking down, major repairs on your car - all of which require a decent level of savings. One of my old bosses always kept enough in cash savings to pay his mortgage for a year if he was made redundant - that may be a bit much but a 3 to 6 month salary emergency fund wouldn't be. Inflation is being driven by the things that you can't save for - food, utility bills and petrol - so your argument that it is better to buy now as your money will be worth less in real terms in a year or so is a little flawed. I bought a TV two years ago for £1,000 which I can now get for £500 so in fact negative inflation on that purchase and the one I bought 20 years ago for £750 (it was a good one at the time) is still going strong and won't be replaced until it finally breaks (it may have a small screen but there is nothing wrong with the SD picture) although I could afford to throw it away and buy a new 3D one.
I agree with Skywalker - don't buy something unless you've got the savings to pay for it. Even if you have take a step back and wait a week or two before parting with your money to work out whether you really NEED (not want) whatever it is you are going to buy. Most household items can be acquired for free (or rather just the cost of picking the up) via freecycle and I can't think of many (if any) consumer goods that are essential to life.
To my mind to buy something (other than a house) intending to pay someone else interest is a bit daft - would you really buy something if it was 20% more expensive ? That can be the same as buying something on a credit card but not paying it all back for 18 months or so.
I could understand the buy now advice if what we bought was British and hence we were supporting British jobs but most of the time the stuff we buy is made abroad !
