It came with a coupon that expired 2 days ago but I got it.
enough in the pack to use more than once if you can prop it up so it doesn't leak out
I have a little holder I put all the open packets in and don't lose a drop that way. Also even when they appear to be empty, I cut along three sides and splay the packets open. There's always more in there. I can usually stretch one packet out for about six weeks. (Just kidding about the last part. LOL)
