Don't see an offer page or banner on this one, but when I added few Bowden Own's products (which are already 30% off), the cart discounts $15 when the total exceeds $100.
Works on clearance items too.
No information on excluded items (if any) and expiry.
I'm getting 15% taken off the price of the item as it is added to my cart. Didn't have to be $100 worth. Has worked for both clearance and normal price, and both store stock and items from the local distributor location. Nice discovery OP!
