Satchmo's administrative interface has this to say about Discount Percentage: "Percents are given in whole numbers, and can be up to 100%."
So I enter 20. The discount appears to work correctly on the site.
Yet satchmo.log produces a dozen of these lines for every pageload:
product.utils WARNING Correcting discount percentage, should be less than 1, is 20.00
I am running Satchmo tip on Python 2.7.2.
