Almost all brands offer a newbies discount code the first time you order, and many offer ongoing loyalty discounts. Don't forget though, it's not the size of the discount but the final price - including postage - that counts. 

And always make sure to shop around as confusingly you might find  other sites selling the same product cheaper than the brand's own site.
