What is your best-ever bargain?

I have so many best ever bargains...the Chulo Pony sample sale just today. (I got a super cute dress for $35) From our trip to Hawaii in March, the pair of $580 Christian Louboutins for $160. My absolute favorite bargain is the $4.99 talula top that I got at the Aritzia warehouse sale about 5 years ago. It's my staple summer top that has been worn over and over again - a pink halter that goes with everything. Weird thing is that I don't have a picture of myself in it. Still...5 bucks!
