Best shops in Germany to buy kid's bike, stroller, car seat

There are many good online shops in Germany selling kid's bikes, car seats and strollers, but few of them offer international shipping.

I've shipped a car seat, a stroller and a kid's bike to Russia from Germany. I liked the prices so much that I have bought more car seats, strollers and bikes for me and my releatives.
