Holland — I realize this is out of your area, but if you don't get any other leads you may want to come this far.
I absolutely love our pediatrition, Karen Locke. She's located on the Northside of Holland. My son is 3 1/2 and we've been with her ever since. I'm currenlty pregnante, and you can guess where that baby will be going too.
In Holland there is a consignment shop called Bumble Bee's. They are located in the outlet mall. They are very organized, and have stricked pollicies about what they accept. Because they closely monitor what they take in, everything is in great condition. I've found a Tommy Hilfigure outfit for my son for like $10-15. I just can't brag enough about them.
Another idea would be to watch for garage sales in your area.
I hope this helps!
