I love shopping at thrift stores and now is the time to do it. Like JC Penney, Walmart, Kohls and such stores, thrift stores do end of season sales too. They usually get a big jump in donations after the holidays and the first of the year when everyone starts cleaning out their closets. That means they have too much inventory and they markdown to make room. Also they want to get all of their winter stock out to make room for spring and short sleeve weather items!
The thrift store I went to marked all children clothes and shoes down to a dollar! I found tons of pants for my son who spends most of his time on his knees playing with cars so all his pants quickly wear a hole through the knees. Also there were Columbia coats and jackets there in great shape (practically new!) I got a spare jacket for him next year for ONE DOLLAR!
Not just the children's section was on sale, the rest of the entire store was HALF OFF EVERYTHING. So I got four shirts of my own for about one dollar too. You should check out your local donation fed thrift store and see what bargains you find!
