Look for items that still have their tags on them - it happens!
You can’t usually depend that anything is arranged by size or style, and seasons are out the window. Try chatting with the workers there - they will usually tell you when the new stock is put out - although some places put it out all day long.
It’s really a hit or miss game - and you have to go in there with the mind set that you might not find anything.
Try to avoid anything smelly or stained - whether it be clothing or household items. You don’t want to bring mold in to your house.
I tend to avoid second-hand shoes from people I don’t know - but that’s just me.
I always wash everything at least once immediately upon bringing it home - just to make sure I don’t bring any unwanteds in to my closet.
Also check out consignment stores. Usually it’s a higher quality, more organized version of the thrift store - because the people aren’t just donating - they are trying to make some money. Therefore the items will often be in better condition. In consignment, they tend to do reductions the longer something is in the store. So if it’s a higher priced item and you don’t “need” it - you might want to sit back and see if you can save some money by waiting for the next discount. Again, chatting with the employees will fill you in on that.
There’s also places like Restore - run by Habitat for Humanity. They have leftover building supplies like paint, tile and cabinetry and other stuff from previous construction sites. Some people also donate household items like tables, chairs, lighting. You can get some great stuff there, and your purchase helps support a worthy cause!
Finally, don’t overlook websites like www.freecycle.org. This is a free posting service where local people post items they want to get rid of, but don’t want to throw away. For example, I often post when I have a couple bags of clothes I don’t want any more. And I posted on there when I needed a sewing machine and was too broke to buy one. It’s free - and you can make sure it goes to someone who really needs it.
The biggest thing is to know that it’s an adventure. As long as your patient and flexible, you’ll eventually find what you want.
Happy thrifting!
