Dave Plowman (News) pretended :
Anywhere offering interest free credit is unlikely to have the best
prices. Don't you check around for prices before buying a large item?

Of course I do. I try to avoid rushing into making a forced purchase.
Sometimes I will have it in mind to buy something, idly doing odd bits
of research before settling on a make and a model which suits. Then I
research costs from various sources.

Our boiler failed a few months ago, so my processing of model research
and pricing was much more hurried. None the less I still managed a very
good deal on the replacement.
