Using the link go to Boots.com and add 3 mascaras to your basket. The mascara is on a 3 for 2 promotion and adding 3 to your basket brings total to £21.96. Use the promotion code MXDH55 and it takes 3 x £3 off bringing your total to £12.96. Select free store pick-up instead of paying the postage charge. You must be signed into Boots.com for promotion codes to work.
