Mazza, you can but different sets and still qualify for the £5 off next and subsequent sets. I bought two sets, different and got the £5 off but I had to pay full price for both sets regarding the postage! You have to buy the same sets to qualify for the saving on postage! One of my sets is the Mayfair, hope my daughter likes it. I have been put off a bit by some of the reviews. I myself haven't used pcmc this year. How good am II saw that and could hardly believe what I was hearing. Also had to switch over because that was the final nail after listening for a few minutes to Keeley stumbling her way through the presentation. But one question… on the buy more, save more, do you have to buy three of the same to qualify or could you get it on one of each? She also mentioned half price p&p but they all have to be the same for that I believe.
