Note: The $5 off $25 coupon says in the fine print “Minimum purchase requirement of $25 must be met with purchases to which no other coupon or instant savings offer applies.” I take this as meaning additional in-store coupons can’t be used with this coupon, so you should be fine with using a manufacturer’s coupon.
