D.H.
If you're going to put money into something, make it in the products they'll spend the most time in and you want to be SAFE: carseat, stroller, & crib. As long as it is safe, it doesn't matter where you buy it from. We bought our whole nursery from Kmart and our daughter is still sleeping in her crib and the products have been great. I don't know about the IKEA crib, but is it smaller than normal cribs? You want it to last as long as possible as the baby grows! (And I'm sure you've been told how fast that will go...) Have fun shopping!
