I see "COSLUS" but my brain says "COLONOSCOPY". Why?

I don't have prime so it was $12.99 for me.

Used code and got $9.00 off, so it works for non-prime members, too.

You can purchase this as a non-prime member....just switch to the "regular price" ($12.99) and add code #XY2K5W4M before you check out. It will apply a $9 discount. The only problem is that you won't qualify for free shipping unless you spend enough (over and above $12.99) to equal a total of $35.
Multiple quantities of this item won't work, since there's a limit of 1.
