I started pricing the cost to replace this toilet it was over $900 plus installed another $500+i can’t afford this .
This is about as good a price as you will get for this size.

Shipping
It arrived a little later than predicted, but in good condition.
Ok - i have had to soak small parts from time in clr overnight to get them de-mineralized in the past.

This will be a great product-but, the box was completely damaged, lid off and product leaked everywhere-virtually no packing-it was a mess!
Competitiveness
I repeated it a 4th time, because why not, and the clr shot out again.
I usually buy clr in spray bottles or smaller refill bottles.
However there are other products currently available for the same purpose some of which can be bought on amazon.
