This mouthwash can stain your teeth - I learned the hard way! Apparently the active ingredient (cetylpyridinium chloride aka CPC) causes brown stains in teeth for some people. It was within three days of use for me, and I went straight to my dentist who immediately recognized the cause and advised not to buy mouthwash with CPC anymore. The stains came off after a professional cleaning, but the whole experience sucked. Hoping this information helps someone avoid the same issue!

The 20% coupon shows up during checkout for me instead of in product page.

I have the reverse problem. I got the 20% coupon (from the S&S side), but not the $1 off coupon (from the one-time purchase side).

Seems like this is super YMMV for everyone; you either get both coupons, or, only one of the two.

As always, read the ingredients and be aware if one has issues. Stannous flouride is another common ingredient that can "stain" teeth.
