Just upgraded my site to 6.4 and it is same issue present as 6.2:

When using quantity price breaks and creating a discount coupon which will apply to only a few categories, the discount code applies to the base price only. The checkout total is wrong and gives the customer a higher discount.

Any fixes? I duplicated issue on the demo CRE site, so it's not my hosting or custom template, as previously suggested. The same in CRE 6.2, 6.3, and now, 6.4.

bump

Confirmed that quantity price breaks in 6.2-6.4 has a BIG bug.

If the product has a quantity price break and a discount coupon is applied to the order total, the discount applies to the base price ONLY (not the quantity price break). This happens when the discount code is restricted to certain categories or products. Somewhere there is a bug in includes/modules/ot_coupon.php and includes/modules/ot_voucher.php, the discount code does not apply to the quantity price break if the coupon is only for certain categories.

Come on guys.....can anyone help me with this? Live store needs help. PM if you would like to be hired or post if you want to help out. A solution will be greatly appreciated.

Hi,

Unfortunately I cant replicate what your suggesting..

Does it happen on both the normal checkout process and if you use the One Page Checkout process?

Yes, it happens on the public demo of 6.4 too. If you had quantity price breaks to the item and then create a discount code that applies to one category only, the discount code applies to the base price (not the price break price). It happens on 6.2, 6.3 and 6.4 (one page checkout and full checkout).

Bumping.... I will be creating a blog review on my experience with CRELoaded this weekend (which was positive until now) and I wanted to know if anybody can fix this issue or if I have to start over using a different cart?

I have also noticed a formatting issue with the Quantity Price Chart on the product page. It throughs off the formatting of the whole page (when Right column is enabled). If I get rid of the price breaks for that product then the formatting goes away.

can you post url to a specific product that you have Quantity Price Breaks on?

Edited: Ok, I found that still had it turned on. Here:

If I turn it off, it is fine.

I had to turn it off, the formatting was too messed up. I will see if I can create a test product and turn it. I will post again if I can do that.
