[TYPO3-shop] PRICE_TOTAL_ONLY_TAX wrong?

[Robert Markula]

Hi!
I use the ###PRICE_TOTAL_ONLY_TAX### marker in my templates. According
to the manual, this marker spits out the "total sum of the items with
shipping and payment costs".

However, I don't know how this marker is calculated in 2.5.6.

Example:
- Article price (only 1 article): 29,90
- shipping: 7,50
- payment: 4,00
sum: 41,40
###PRICE_TOTAL_ONLY_TAX### output: 4,12.

That's not correct, it should be around 7,00.

Is this just a wrong thinking on my behalf, or is there something wrong
with this marker?

Cheers,
Ro
