PriceBazi: Volume Tiered Price

UPDATE*** They contacted me very quickly and fixed the issues.
The reason it isn't 5 stars is a) turning parts of it on/off needs to be done in the code and not a checkbox to torn on/off and b) a little difficult to understand the settings and some complications in using the collections Issues: 1) Does not work period. a) not showing the graph on the product page and b) not showing the discount in the cart or at checkout.
2) Customer Support -- the only way to reach them is via ticket. I had to create a account with their ticketing software and when I tried to make a ticket discovered that this APP isn't listed as 1 of their apps. I had to tell them I am using a different app.
After creating the ticket, I received an automatic email asking for my shopify admin username and password and that I befriend someone named Mahmud on facebook. I would normally wait for a response before giving a bad review. I will update IF the issues are resolved in a timely fashion. The reason I didn't wait is because their ticket system doesn't support this product of theirs.

So far so good! Needed help with the install on my theme and they were quick and responsive! Customer service rocks!

Great App! It solveed some really specific requirements from my business model! And great customer service!
