Great product. Short on quantity by nearly %20!

I have had nothing but 5 star reviews for Sticker Mule for quite a while. And I order A LOT from SM. But today my order of glitter stickers was short nearly 20% on quantity. I could see maybe being short 1 or 2 stickers. But short 8 out of 50? C'mon. That is plain sloppy. I have had this problem multiple times in the past. But I thought the issue had been resolved. So I stopped counting quantity when it came in a while ago. Now I am second guessing myself on not counting all the recent order quantities. And if I should have counted each quantity. Instead of trusting that Sticker Mule would get the quantity right... SM had gotten all 5 star reviews from me for many orders. But I will now be going back to counting every order from now on that comes in. Because it is clear that SM can't be counted on (pun intended) to get me the correct quantity. I am disappointed this is happening again to be honest....
