They are the worst company known to man. Scum who target the lesser well off members of society.
They're still in business though, which is a shame all around.
It's an incredibly successful business model that several companies use to great success.
I believe even a 3DS comes to around £600-700 with Brighthouse's "cheap weekly payments".
Infact...
Xbox One with Forza Horizon 2= £1625
Vita Slim = £844
Nintendo 3DS XL (old model) = £676
But I agree, it has a swimming pool full of ethical issues.
I have a friend who buys white goods from Brighthouse because she has a bad credit rating, my credit rating isn't great either, but I would never, ever, resort to Brighthouse.
