15% off mega blocks + playmobile, 20 off costumes + 10% off 1st order plus free shipping at Yogee - Nice offer stack.
I've just been through the process and tested that the Playtime 10% off does combine with the 15% / 20% off. I added two mega blocks to the cart and the 15% off was auto applied. Because I was logged in as a playtime member I got the additional 10% off. I missed out on the free shipping as my order total was $67.84 but hey ho... its still a decent offer stack.
