Look online or ask someone at the store if they have a sale schedule of some sort. They may also have demographic specific sales, such as a percentage off on a particular day of the week for military, students, seniors, etc.
THOROUGHLY CHECK ITEMS
Make sure to try on clothing to assure that it fits properly. Even if it is the correct size, since it has been previously owned, it may have been shrunk with improper washing or just worn and stretched.
You should not only research an item’s retail value if you hope to resale it, but its resale value as well.
Check the Valuables – Most thrift stores have a case in the store where they keep jewelry and other valuable items locked up.
Negotiate – If you find an item that has a tear or some other needed repair, that you feel you can replace or repair, don’t hesitate to ask for a discount.
