I haven't been there, but here are some other places I've been to:
Kids Junction, Both Kid-to-Kid locations, and two Green Baby locations. Also, my MOPS group is having an Everything For Children sale on April 24 at Concordia Lutheran.
If you don't need anything right now, you should totally wait for the Concordia MOPS Everything For Children Sale. The selection and prices are way better than any consignment sale.
It's April 24th from 8:30 to 1:00 at Concordia Lutheran Church on 1604/Huebner.
