Yes, everyone but one person I know shops for great sales at thrift stores.
Soap works. Vinegar or bleach added into a wash load also sanitizes that load if you don't think soap works. Drying clothes in a dryer helps to sanitize clothes...
No matter what sort of clothing it is, undies, bras, slips, dresses, pants, or more, they are clean as when purchased when they've been laundered correctly.
I don't think I'm going to get cooties from putting on something that touched another person's body.
I have a friend who is a germaphobe. She almost never even buys anything in the stores because they might have been tried on by someone else. She orders most everything online and has it delivered to her home, for her whole family.
I never buy anything at a second hand shop and wear it without washing or dry cleaning it. That would be gross.
For pricing. Rich people who like designer clothes don't often shop at thrift stores, they do sometimes make donations. My mother in law went to the Salvation Army thrift store one day and found a whole load of Harve Bernard clothing. Suits, blouses, skirts, and more. There was also a whole rack of Clark shoes. Someone must have passed away and their family had emptied out their closet. She bought everything that fit her. The tops were $1-$1.50 each. The Clark shoes were $2.00 a pair, right along with everything other pair of shoes in the store.
My mother in law spent over a hundred dollars in that store that day and walked away with sacks and sacks and sacks of designer clothing that she loved and wore the rest of her life.
If those items had been overpriced for "where" they were then they wouldn't have sold.
For the most part, everyone who shops at thrift stores need to buy things that are a great deal. Not find half priced things.
I go to a few thrift stores in my town. A couple, that I don't frequent, price their things way too high. I mean, I can go to Walmart and buy the same exact tee shirt, same brand and size and everything, for $3.50 and those thrift stores will have it priced for $5. Ummmm, who's the idiot pricing your items?
People want things for pennies on the dollar they cost. So keep the prices down and people will buy them. One of the stores that I do go to almost weekly has a ton of things priced a dollar.
On Monday it is Senior Citizen Day, they get 30% off their total bill.
Tuesday it's Half off the yellow sticker items. These are the items that are expensive items like new items that still have the tags on them and they paid $90 for a dress...higher cost items. They mark them up but expect them to go out the door at half the price marked. They don't often sell these items though. I've seen them repriced for that half price many times so when they are actually purchased they got half of the half price they originally marked that item. Then sometimes they still don't sell and they mark them a dollar and they get bought.
Wednesday is sack sale day. Anything you can stuff into a plastic Walmart sack is $5 or less, depending on how much stuff they need to get rid of. It's been all the way down to $2 sometimes. Like when the seasons are changing and the racks are full of long sleeve sweaters and heavy items. They need to get the donations out that are for warmer weather so they just need stuff gone.
Thursday is 20% off day. Anything that does not have a yellow tag is on sale. I can get so many things for 80 cents on those days. That's where a lot of the kids play clothes come from.
Then on Friday it's something else. I can't remember because I don't often get in there on Friday. But Friday is most people's pay day so they want them to come in and pay as much for items as they will.
So keep your prices down.
