Thou shall DIY: Maybe your name is Jenni Radosevich, or you’re Edward Scissorhands’ long-lost twin sister in the sewing room. Either way, view the thrift store The Art of Thrifting as a cheaper alternative to a fabric shop, and view each item not for what it is, but for what it could be. That oversized dress with an awesome print? Snip away to make an awesome blouse, or a mini cocktail dress.

Thou shall haggle: It may or may not work, but it’s worth a try because you know what’s better than an amazing Theory blazer for $10? An amazing Theory blazer that’s $10 and 30 percent off because it’s missing a button.

Thou shall search for new tags: We normally perceive thrift stores as a used Target of unwanted, abandoned and yes, in some cases, unusable stuff. Yet, hold on there, Batman. Not so fast. Keep in mind that tons of people buy clothes they will never wear. (Yeah, target-weight skinny jeans, we’re talking to YOU!) Or retailers often donate unsold merchandise to local thrift stores, so keep an eye open for those extra-special goodies.

Thou shall not be afraid to go home empty-handed: When you’re in a wonderland of dollar goodies, it’s extremely tempting to want to snatch what you perceive as deals. Yet, even if that DVF vintage blouse is only $5, if it’s four sizes too big with yellowish pit stains, it’s not a deal. In fact, it’s a waste of five bucks. This rule applies to any sort of shopping, but especially when it comes to thrifting. Don’t be afraid of leaving the store empty-handed.
