Basket rule / send a gift with other discounts -> wrong amount

[rricci34]

I noticed a bug on a PS 1.7.6.5 (so blank test).

When creating a basket rule of the type "send a gift" (therefore a product) from a minimum order amount, the reduction amount becomes incorrect if we add a second (or more) basket rule an amount. However, the amount of the reduction is correct if it is the only one to be used.

For information :
I created a basket rule which is a gift product that I defined at 10 € (so that the calculations are simplified)
I created a second basket rule which is an amount of € 10 including tax

Here is what is happening: (I am enclosing screenshots that will be more telling)

The 2 basket rules:

If 1 rule amount of reduction OK

But when I add a second rule the amount becomes wrong (besides I do not understand the latter which is not proportional to the amount of the reduction (after several tests):

Hello,

Despite our efforts, we were not able to reproduce your issue with the provided information.

What is your php version ?
Could you send me a screenshot of the two cart rule created

Thank you!

Hello, is one of your discounts a gift product? (Pull imprimé colibris for example) which is added automatically from a certain amount?
The 2nd reduction is a simple amount.
I enclose the screenshots.

1st rule which is a gift:

2nd rule which is an amount :

I just did a new test look at the amount of the reduction is not good:

I use for information PHP 7.2

Hello, i tried to reproduce the bug with the exact same rules that you created and unfortunately, i can't reproduce it:

• Free gift discount can't be applied because there is no code written in informations tab even if you don't normally have to write one for your case

When i enter a name of the code, here is what happen:

• 1st rule (free gift discount): it adds the same item but for free -> but you have to enter the code in your cart (FO)
• 2nd rule: 10€ discount -> works perfectly

Here is a screenshot:

Hello, this is crazy. I have this bug on a production site and also on this prestashop 1.7.6.5 in a blank room.

I am attaching a video that may be more meaningful and may allow you to see what is missing ...

Do you have specific discounts on your product page?

Can you provide us screenshots about your product page configuration:
Catalog > Products > Product page

• Shipping
• Pricing
• Options

Hello, however, I have not changed anything in the basic configuration of this new installation of PS 1.7.6.5. I leave everything by default, without additional module in order to precisely carry out my tests ...

[rricci34]

I just did a test on 1.7.7 (beta) and it works correctly.
Do you test on PS 1.7.6.5?
Thank you

[rricci34]

Well, I just did new tests on a fresh 1.7.6.5, and I no longer have this bug. I do not know why but the main thing is that he is no longer there.

Sorry for the delay :/

I'm glad that it works!

Since you no longer have this bug, i can close this issue.
