DUAL Pricing v2

[jjj0923]

EDIT: First of all many thanks for your help, i really appreciate it.

I think i managed it, althoug there's an error with the TAX calculation. I've made a testorder with customer whole sale customer.

1. Login as a whole sale customer
2. Prices still shown including taxes
3. Added 10 products of $2.98 = $29.80
4. Added 10 products of $3.57 = $35.70
5. Shopping card displays amount of $65.45. This is wrong should be $65.50
6. Go to checkout (Step 1)in store, shipping cost are added
6. Continue checkout; Sub-total is displayed (Step 2): $ 65.50 which is correct
7. Shopping card sidebox still displays wrong amount
8. Last step, the amount is still correct
9. Order confirmed

So, I think there is an error with TAX calculation. Although this line shoud be ok: $tax_add = ($products_tax/100) * $shown_price;

EDIT 2: Logging in as a "normal" customer the prices are displayed are correctly

since there should not be any tax to wholesale why not just set it to zero
and
I guess it begs the question - was there a sales tax error calculation problem before you modified any of the code. perhaps the differences in a few pennies could be some sort of rounding error that you discovered in 1.50?
