How can I apply specific decimal discounts on bulk purchases?

[smiscio]

I need to have a discount of 19.53% but it only lets me put in 19% or 20% (no decimals)

How do I change it to allow decimal places?

Here is why - Each product is $1.49, but if they buy 10 I need it to be $11.99 which is a discount of 19.53%

This does not work, nor will it ever be added. Just put in a discount of $2.91, or put it in for 20%, like the title of your discount reads. "Buy 10 Seed Sticks - Save 20%" means 20%, not 19.35%
