Super easy to manage all the discount rates for multiple products, had a delay with customer service due to a public holiday but as soon as they went back to work they fixed my issue right away.
Tote Bags in Bulk
Big deal for our sites' reputation: The math of the discounted item price was wrong on the cart. I have observed it was adding 12 cents out of nowhere. (if your items cost less than a dollar and if you sell items in high quantities like 500 or 1000)
Not a big deal: cannot make the word "off" lowercase on the cart page, because its hard coded its not a custom variable.
It will be an acceptable app after they fix the math for the item discount in cart; will be the greatest volume discount app after they add the Per Item Price column to the discount table (the one that is displayed on product page)
Laced Shoe Inc
The customer service is excellent. They responded promptly to my emails when I had an issue. The app is simple to use.
