While there's no “perfect” day to shop second hand stores, many regulars swear by shopping early on Monday and Tuesday. Homeowners tend to drop off garage sale leftovers on Sunday nights, making for new finds. Plus, the weekends are more crowded shopping days, so employees look to restock early in the week.

In the simplest terms, the strategy behind thrift store flipping is to find items you know you can resell for a higher price. The goal is to find an item at a thrift store and then sell it on an online platform like eBay or Facebook Marketplace at a decent markup that makes this a worthwhile side hustle venture.

Thrift store prices are low, but that doesn't mean they can't go lower. If you think something is priced too high for what is, ask if they're willing to take less for it. Just be polite in doing so and don't be discouraged if they're not open to bargaining.

1. Save Money. The clothes that you acquire at a thrift store are much cheaper than when they're brand-new with tags. Some items in the thrift store may even have tags on them, signifying that they've never been worn.
