PetSmart cuts $10 off orders of $30 or more. (Discount applies in cart.) Plus, it stacks with already-discounted sale items. If available, choose in-store pickup to avoid the $4.95 shipping fee, or get free shipping on orders of $29 or more (after discount). (Large items may have additional charges.) With such a low minimum purchase requirement, that's one of the best dollar-off coupons we've seen from PetSmart in the past year. (For further comparison, we last saw a dollar-off coupon for $20 off $100 in September.) Some exclusions apply. Deal ends January 30 at 6:30 am ET.
