Attack of the apostrophes

Christmas can always be relied on to give us an attack of apostrophes as shops battle for the festive shilling.

We all have a laugh at the local greengrocer and his hand written signs offering collyflower's and spud's, my favourite was some years ago when I spotted 'Cox's apple's - loverly heaters', but surely national chains must have someone on their staff who can claim literacy among their attributes when it comes round to the annual appraisals? Apparently not.

Thus Boots are telling us about offers on 1000's of gifts while Currys Digital implore us to save £££'s. What it actually is of £££ that needs saving is not made clear. It must be very confusing for their marketing and advertising departments though, what with plural and possessive both starting with P, but then again so does that other fine word . . . prat.
