J. Crew is offering 30% off sale purchases in stores and online (use code MUSTHAVE) until Monday, July 9. A warning, the prices are final sale. Teachers, remember to take your teacher ID card with you to receive your extra 15% off, totaling 45% off the sale price! The J. Crew in Las Vegas has been more consistent about offering the teacher discount with promotional sales. I hope teachers in other cities are able to get the same deal.
