The problem with GPS

[mcflurry]

...is that when companies "buy" postcodes, it ends up directing you off course :eek:

Twice now we have ended up in a residential area streets away from the shop. The shops have bought the last 3 characters, for example if Pistonheads was in Central London it might have W1 1PH, rather than W1 2AB (made up)

Annoying evil postcode things :furious:

That's a very useful point to remember - and a good argument for not worrying whether a database has full codes available.
