Maybe they're spending so much in large amounts to not go over the savings limit for certain benefits? Either way they're on the fiddle somewhere, that degree of spending is beyond normal especially for a very large family that supposedly relies on income from a pigging pie shop.
Somebody mentioned her kids being too independent got DLA, I'm sure Noel and Sue would lie their arses off on those forms for a bit of money, they've lied to get the whole family disability fast track passes after all.
Poor Tillie and Max, why couldn't she make them a calendar they'd like each? Books, stationary and vouchers would have gone down a treat (we know laziness is the answer, I know)
