Anyone??

Am I missing something. I thought this issue would solicit some response or is it normal for a shopping cart not to add up the totals correctly. If you are using the shopping cart, do you simply ignore this, or are you not aware, or does it not manifest itself in your webshop?

Hello Richard,

Not everyone who uses eZ Publish uses the shop module.

Also it sounds like (from the lack of response) that others are not having the problems you describe. I honestly have not encountered the problem you describe.

You might be better served by posting a new issue at http://issues.ez.no/ezpublish

Cheers,

Heath

Hi Heath,

Thanks for at least an acknowledgment. I have already raised this as an issue #017667, a couple of weeks ago, and applied a priority of medium. My concern is that for all those using the webshop, they might not be aware of the problem, you naturally assume that it is doing the calculations correctly and do not double check with a calculator. It was not until I entered orders created by the webshop into a different accounting system that the problem became apparent.

It is easy to recreate the problem. Simply create a product with a price of 99.99. Apply a discount of 30%. The new price is displayed as 69.99 (69.993 rounded). Add it to your basket, change the quantity to 2, and already there is an error. The shopping cart will now display the total as 139.99 (69.993 *2 =139.986 rounded up) , not 139.98 (2*69.99) and the customer is being overcharged. I have tested this on 4.02, 4.2 and 4.3.

This has to be happening to all webshop users who are applying sales tax, or discounts. Should I change the issue priority to high as overcharging customers is not a good feature of a webshop?
