Bests & Worsts Reviews from Amazon

We bought this item in Apri for $12.99 and received a 160g tube. We needed some more so I searched my orders and clicked on the same item. I assumed I was ordering the same item. Imagine my surprise when for $10.44 I received a tiny tube with 20g of toothpaste. That 12.5% of the size of the original for 80% of the cost. I'll be looking elsewhere for my next tube. We like the product, but this price gouge is unacceptable.
