I can't believe a lot of the reaction here is criticising her for dealing the £8k - I think it was totally understandable.
I think her train of thought at the £44k offer will have been something like: "Well, if I keep the £250k in play, the offer will be in 6 figures if one of the mid-reds stays with it, and double if it stays with a blue. If it goes, there's still two mid-reds there, so there'll still be a decent 4-figure get out deal which I'll still be happy with, and only a 10% chance of complete disaster, so I may as well give the HUGE money a shot".
While it's not what I would have done, if you think of it like that you can justify the way she played it! Just a shame she avoided the 10p rather than the £15k - the last box coice cost her £12k!
