3. For the address, choose Country = Canada, Province = British Columbia.
Taxes for this location are GST (5%) and PST (7%). They should be $15.50 (5% GST) and $21.70 (PST 7%). Instead they are being calculated as $16.40 and $22.96.
Tax calculations are correct when non-bundled products are added. Only product bundles are causing a problem.
When product bundles are added to the cart, the tax calculation is no longer correct. Site: https://oceansev.com/
For example:
1. Add a bundled product to the cart, such as this one: https://oceansev.com/product/spirit-1-0-plus-bag-set/
2. Go to the checkout page.

Hi Eric,
I see that you are using a discount of $18, so this discount is not taxed. You should switch to using a percentage discount, for example: 5.48780488%

The problem is that the tax is being calculated on the final item price ($310) incorrectly. 5% of 310 is 15.50, not 16.40.
Is this a bug that causes any product bundles using non-percentage-based discounts to incorrectly calculate tax?
Yes, that's right. Our plugin doesn't calculate tax on the discount. So it will calculate 5% of $328 = $16.4.
Best regards,
Dustin
I understand that it's calculating incorrectly. Will you fix this bug?
