Depending on your location
If you smoke 20 a day, you will save around 230 quid a month (double that if the spouse smoke).
If you like your booze, Smirnoff blue label 1 liter is 9 quid abroad. It at least 25 in the UK.
If you want to buy a car, you get it thousands cheaper (possibly tens of thousands depending on your budget).
Most non consumables are VAT free.
As mentioned before if you have kids, they are almost guaranteed CEA or be educated at international schools whose fees would rival some of the top private schools in the UK.
The housing is usually local, which means when there is a fault, they get off their arse and fix it, none of this "We'll be around sometime in the next 10 days and still won't fix the fault".
People aren't going to give it up because of a cut in LOA.
