I use the FF pressed powder - which I love, but it's £20 per compact (!!!) and my nearest largest Boots doesn't sell it anymore. (Tried e-bay, but they don't have it, and although Debenhams does sell FF they have limited shades, argh!)

So are there any other brands for darker skin which are:
a) easily available
b) cheap

Everywhere I go, I can never seem to get a shade dark enough for me - where should I be looking?!

Thanks
