Great Mod, but it seems to be a bit wonky with how it is handling tax.
I am testing on a fresh install of 1.3.8a using 3.13 of this mod.
Instead of adding the tax to the tax line it adds it to it's self in the insurance line?
My tax rate is set at 9%. and Insurance is set at $5.00 and shipping is taxed.

Sub-Total: $110.00
Flat Rate (Best Way): $5.00
Shipping Insurance: $5.45
WA Sales Tax: $10.35
Total: $130.80

If I set Display Prices with Tax to true it adds the the tax to it's self twice.

Sub-Total: $110.00
Flat Rate (Best Way): $5.00
Shipping Insurance: $5.90
WA Sales Tax: $10.35
Total: $130.80


The math for the total is correct for either situation. $120.00 x .09 = $10.80 so the total $130.80 in either calculation is correct.


Thanks,
Jim
