To prevent coupons to be applied to sale items, you can use this option: http://cld.wthms.co/CguDVH
To apply a 10% sale to all products is a bit trickier. You could do this globally, but then the products may not appear on sale at the product level and only in the cart. Also goes against the above coupon setting.
So the better option it to set an actual sale on each products with to/from sale dates.
I would recommend using the CSV import/export maybe for quick editing of all products: https://docs.woocommerce.com/document/product-csv-importer-exporter/
Alternatively, I’m sure there are plugins that could help with this. Found this one with a quick search: https://wordpress.org/plugins/woocommerce-bulk-percentage-pricing/
Hi!
Thanks a lot for your answer.
I have installed the plugin woocommerce-bulk-percentage-pricing/ and insert there 10% and press the discount prices button.
Then I have in each product the saleprice.
It works fine.
But how can I deactivate it.
I tried to insert 0%. But then I have in saleprice the same price as in normal. But the saleprice should be empty.
kindly regards
That I’m not sure about, you’ll need to ask the plugin authors.
Otherwise, you can export products and bulk edit the sale price column to be empty.
