Account Invoicing
I happened to notice a discrepancy on my Order Confirmation email - the total was correct but it didn't show the amount I paid for a discounted Gift Card, went in to compare it with my account and that showed different individual prices for items with the same correct total. In fact the Invoice page showed one set of prices and the Order Complete page another set, and neither showed the discount on the Gift Card. I raised a ticket asking that the Account showed the actual amount I paid for items and was told that it had been raised as a feature request with the webteam already, but if I raised it here and more people requested it it might help. So we you like to see the Account page correctly displaying the amount you paid so you can go back and check anytime? CS were able to give me the correct amount paid for the Gift Card, so the data is available, just not visible in our accounts.

I raised that problem with Zendesk March 17, 2014, 05:09 ...
After some messages and screenshots back and forth I was told on April 8, 2014, 10:44 that this problem will be send to the web team ...
Save your emails ...
that's all I can say ...
I do screenshots most of the time (I try to remember) of my cart before I check out. I don't return many products, but I want to know exactly what contributed to the total amount. They changed the cart over a year ago, to the customers' disadvantage. You should be able to have a receipt that matches ver batim what was shown to you when you checked out. I don't think mentioning it here will do diddly squat as the programmers of the modules don't read the forums for our opinions.
Well, contacting support didn't do anything either, so we can try here ... after one and a half years, maybe it helps?
CS suggested posting here to get more people to log tickets and hopefully get the the problem fixed because there is more demand. I would think the Professsionals would require accurate billing.
I save all confirmation emails for at least a month because, except for memberships and gifrt certificates, the confirmation emails show the actual price paid for each item. That way I can go back to the email to determine the price in case I need to return an item or it is offered at a lower price later.
A feature request? Why the blankety-blank should we need to put in a feature request for a basic function of the store software that should have been in there all along? Since the changeover, I've been convinced that the problem is that the store software is just incapable of adding and discounting, but this is pushing me back to my original opinion that the store installation has been just plain broken from the beginning, and nothing short of a reinstall will fix it.
I don't think it's fundamentally broken, Magento just has a reputation of being a nightmare to figure out. Like someone said in a programmer's forum: "Just thinking about the Magento platform, makes my body cringe with great horror."
