For its My Panera Rewards members only, Panera Bread cuts $3 off when you place an online Rapid Pick-Up order of $6 or more and apply coupon code "RPUF2". (Not a member? It's free to join; click the My Panera tab at the top of the page to display the "Join Now" button.) That's tied with our June mention as the best coupon we've seen from Panera in the past year. Deal ends November 6.
Of note, this code may be valid at select locations only.
