Are you tired of all the cookie deals today?? This is basically a filler to get to 5 items and max 15% discount. Coupon on product page is only one time use, but even after that multiple orders is still a great price around $2.55 as I bought these at Publix last week for $3.50.
Edit: It appears 15% off coupon is a YMMV. So without coupon it's either 2.85, or 2.55 with 5+ subscribe and save.
