Great topic. Around here, the thrift stores all have sales where items with a certain colored price tag will be either 25% or 50% off on a certain day. One day my teen daughter said she needed new jeans and I suggested we try the thrift store. She didn't want to because it isn't "cool" to wear used clothes and what if the person who donated them recognized them? But I told her we had to stop and look there on the way to the mall anyway so...she found a pair of brand new jeans, still with the tags on them, and they were marked $10 but had the right color tag to be 50% off that day. So she got a $60 pair of jeans for $5. She buys all her own clothes out of an account I set up for her just for that purpose, so she was thrilled with this find as it left a lot more money in her account she could use on other things. She's better about thrift store shopping now....
Just last week my son needed new clothes to attend a wedding since he's grown several inches this year and outgrown all the other "nice" clothes he had. Once again I hit the thrift store and found him a pair of black slacks and nice button down shirt. Paid $3.75 for both. It wasn't until after I got home that I noticed the shirt still had tags attached....
