If you're going to be a smart arse it's £260 or 350 Euros (£302 by todays rates) - whichever they feel like charging you.
They are making a profit from it and that, regardless of the amount, is laughable. It is for recruitment for goodness sake, if that doesn't tell you they don't have any requirement for people I don't know what does.
As I have said really think about what you are getting in to, the 737 Tr is absolutely f-ing useless unless you have ALOT of hours and then it is just f-ing useless - unless you want to work in one of the worlds arsehol*s or for one of the worlds arsehol*s. Turkey? Nigeria? Indonesia? The Emirates really? Ryanair? Wonderful, well worth the effort.
Don't waste your money, hold tight, better things are around the corner - whenever that corner maybe. Fools rush in where angels fear to tread.
