Saucony is offering 20% off everything^ until midnight November 13 with the promo code FRENZY20.
Based on my tests, the 20% off seems to also apply to already reduced items which is very nice.
Free shipping for orders over $100, otherwise it's $10 shipping (flat fee). They also offer free 30-day returns.
^T&C's apparently apply but I haven't found a list of exclusions
