Whenever I want to justify buying something like this I just compare it to the price of a meal out of the kind decided on the spur of the moment, rather than an arranged special occasion.
A curry for two, a few beers and a taxi home on a Friday night is easily going to be more than this, so buy it and the next time the urge comes on, remember to say to 'er indoors "I'm not really feeling like going out tonight, can't we just curl up in front of the telly instead?"
