I did a clean install of Zen Cart version 1.3.7. I noticed that I was coming up short for tax when a coupon is used. This only happens for orders that I have to collect tax for. From what I can see, It seems to be deducting the coupon twice, then calculating the tax on the remaining total. I end up short almost 90 cents for each order.
Does anyone know how I can fix this?
Thank you,

Except I don't know how it's calculating tax - it's not coming out the way you described it.
