On a recent trip to a Games Workshop i picked up the Easy to Build Plague Marines. For €12 this is a cool little box to pick up. It has 3 of the new plague marine models that are snap fit and easy to put together.
If you're like me and like to pick up some random models this is handy to pick up but it also gives you a chance to see some of the newer models without buying a €30-€40 box. Other available boxes are the Primaris Marines Intercessors, Reivers and the Poxwalkers.
