I got this BB cream sample set in the post today and it's fantastic. I actually got 2 free samples (a moisturiser and a CC cream) so 14 samples in all which I think is amazing value for under £5. I paid £1.64 for shipping with a tracking number and it took about a week to get here. The website has other sample sets too including skincare.
I've tried this so far and like it a lot, it's rather like a blurring and brightening moisturiser (I wouldn't wear any moisturiser but some aloe gel underneath and I have quite dry skin).
