When the quantity of a product is updated in the mini-basket, only the price of that product is updated and any other products are left unchanged. This causes problems when discounts are applied across products (e.g. Buy X get Y half price).
We use a plugin that allows us to offer bundles. They’ve investigated whether they can help from their side, but concluded that the issue was with the mini-basket only updating the specific changed product rather than the whole basket.
Pricing rule applied in the use-cases below: ‘Buy X get n% off Y’; the discount can be applied multiple times if the conditions are met.
The problem: Updating quantities of Product X doesn’t trigger a recalculation of the price of Product Y. The price is only updated once the page is refreshed.
See links to examples of product X and Y below (private content):
We have a screen recording showing the two use-cases below: https://we.tl/t-bMwWjBXEUm
To replicate:
Use-case 1a:
1. Add 1x ‘Product X’ and 2x ‘Product Y’ (discounted product) to the basket.
2. Open the mini-basket and observe that the discount is applied to one of the two Y products (correctly)
3. In the mini-basket, increase the quantity of Product X
4. Observe the price of product X doubling (correctly)
5. Expected: the price of product Y should also update to apply the discount to both Y products.
Observed: the price of product Y doesn’t update. The discount is still only applied to one product
5. Refresh the page and open the mini-basket
6. Observe that the discount is now correctly applied to both Y products (as expected)
Use-case 1b:
Similarly, if you then reduce the quantity of Product X back to 1, the discount isn’t removed from one of the 2 discounted products.
Can you please help us fix this so that when a product is changed in the mini-basket, the prices of all other products are updated too?
Thanks,
Shira
