One of my friends posted on Facebook that The Children's Place is having a great clearance sale right now, and it gets even better when you use the coupon code RETAILMENOT1C for an extra 15% off. Many items are $5 or less. If you need some items for next fall/winter, it's worth checking out.
Yesterday we ran to Target to pick up a few things, and they had a lot of things on clearance too--especially toys leftover from Christmas for 50% off. Winter boots hit clearance, but I stopped by a little too late and missed out on the selection (only a few sizes were left). The clearance racks were packed with kids' clothes.
I've blogged before about Sears' KidVantage program (where they will replace clothing and shoes that gets holes or tears in it while the child is still in that size). If you have time, it may be worth checking what's on clearance at Sears (prices may continue to get lower up until March). If you can get a brand-new shirt for $2.50 (or less), and you know if anything happens to it, the store will replace it with something similar, that beats thrift store prices.
Have a great day!
