Me? ~£120. ~£30 each on ms wza (we set a limit, cos we've had two weekends away in December as 'a present to each other'), my sis&her bloke, my mum, and my dad. I guess you can add a few quid for wrapping etc, and the odd random choc/wine gift that might be needed.
(No room for coyness here. If you're not fessing up, it's obviously way too much.)
