BENEFIT cosmetic discount codes needed for shopping online?

Hey guys and gals, I am trying to earn myself a discount for the wonderful cosmetic brand ‘BENEFIT’, the website is www.benefitcosmetics.co.uk
I purchased some stuff yesterday from there and got a free makeup bag, and in a separate transaction used my more magazine discount codes which were ‘MOREDELI’ for free delivery and ‘MOREOFFR’ for 15% discount. I tried using the same discount codes again today but they’re not working for me, I think it’s because I have used them once already. Anyone know any others I can use? Or even a website where I can buy it cheaper (other than ebay)? Thanks
