According to owners and cashiers, thrift stores see huge donations during spring and summer. That’s presumably because this is when people prefer to declutter their homes. If spring cleaning is a major event in many households, you can bet you’re going to see a lot of great new stock.
Another reason for this is the prevalence of garage sales. Nobody wants to set up shop in the dead of winter or during cold, windy autumn days. Leftovers are usually packed and taken to thrift stores.
