Another Boots cosmetic glitch- as selected Max Factor items are on a save as well as 3 for 2 it deducts more than it should at checkout.
Miracle Touch Foundation RRP £9.99 each, add 3 to basket and it comes to £10.98 and also adds 3 free perfume samples.

Miracle Match Foundation also RRP £9.99 each, add 3 to basket and again it's £10.98 with 3 free perfume samples: http://www.boots.com/en/Max-Factor-Miracle-Match-Shade-Matching-Foundation-30ml_1697455/

Smooth Miracle Primer RRP £10.99 each, add 3 to basket and it comes to £15.98 although no free perfume samples: http://www.boots.com/en/Max-Factor-Smooth-Miracle-Primer_1876206/

Masterpiece Max Mascara RRP £7.99 each, add 3 to basket at it comes to £9.98 and also adds 6 perfume samples!: http://www.boots.com/en/Max-Factor-Masterpiece-MAX-Mascara_38454/

From what I can see the perfume samples are Lacoste and Marc Jacobs. Also free C&C so happy days, hope this helps somebody!
