Is this the end?

A few days ago I took part in the Get your face on party over at the stories of a to z and I posted about my make up regime. I got many responses about the lash and brow gel I use instead of mascara. I check periodically to see if it is on sale. Well when I checked today it was not in the mascara section any more and when I typed it in the search box it came up at the rock bottom price of 4.00$. I was very excited about the price but bummed out that it was not coming up on the main page. I think it may be on its way to being discontinued.  This is the the third makeup item in recent months that I use to be discontinued.  I am buying enough to hold me over for quite a while but what will I do when I run out?  What do you ladies do when your makeup favorites are discontinued? Find a replacement, Beg the company to keep making it, or just forget about it?
