On a several occasions I have been asked where and how I get such good deals on children's clothing. Here's the breakdown:
Online: (More convenient and we all love packages, don't we?)
Kohl's- I've gotten a few darling outfits for my daughter here for $6 each. Upromise rebate and more rewards if you have a Kohl's card. (I can't tell you what they are, because I don't.) Limited coupon stacking.
In stores: (No shipping charge or minimum, yay!)
JC Penny- They often have super cute baby clothes at good prices.
Macy's- I've gotten a few super amazing deals in the kid's department if your timing is right. 4-piece outfits for $5, little dresses for $3.
Old Navy- I actually don't shop there that often. Online prices are always better, but there is the occasional sale....
Costco- Best place for kid's pajamas and little girl's Christmas and Easter dresses. The Carter's fleece footie jammies are about $7. Although, here you run a great chance of having her wear the same dress that the neighbor girl is wearing.
Ross- Not always the best selection for kids clothing in the size you need and less reliability, but I've found my best shoe finds here. Skecher's for $15
