Wow, Stila is offering a week of pretty amazing Back to School promotions starting this Monday. They start with 35% off, and reduce the discount value every day until Friday, with 20%.
If you're planning on getting anything, start making your list now so that you can take advantage of the steepest discount come Monday! I have a feeling stuff will sell out fast.
No code is needed, apparently, and it doesn't apply to gift sets and sale items. It doesn't indicate anything about the free shipping for orders over 50$, so presumably that still applies?
Unfortunately they don't ship to Canada, but if you have a US buddy to co-order with, or you use a mail-forwarding service, this is a prime time to stock up on staples or splurge on those limited items you've been eyeing.
