Thanks for that explanation, smaugsbane.

I suppose, then, that to work out a break even point using both texts and minutes as factors, you knock off one minute in exchange for two texts?

That would work. 

If you want to calculate it, it's::

   £5 + mins x 2p + texts x 1p   <=   mins x 8p + texts x 4p

Easiest way to solve that is to fix one of the types of cost - either minutes or texts - and plug in the numbers. So for 50 mins you get:

£5 + 50 x 2p + texts x 1p <= 50 x 8p + texts x 4p

Which is:

500 + 100 + texts <= 400 + texts x 4
600 + texts <= 400 + texts x 4
200 + texts <= texts x 4
200 <= texts x 3
66 <= texts

So for 50 minutes and 66 texts you'd be better off without the labs goodybag, but with 50 minutes and 67 texts the labs goodybag works out cheaper.

I'm sure someone already has a goodybag calculator out there with the labs goodybag on it - anyone have a link?
