Something is happening and I don’t know why. In the shop I am developing I have put some tier price for quantity discount in some product. I was working fine. However, I decided to change the products price and remove tier pricing. In the products page there is now no mention to quantity discount, but in catalogue listing, there’s still the “From: XX,XX€”. It does not go away!
It also happens if you have a maximum tier discount, and then remove that figure and tier, that figure will always remain as a “as low as” price.
I know it’s not the answer you were looking for, but;
I searched through all the Mysql tables I could find, cleared all caches, with no sucess, and finally deleted the product and re-listed the product, thankfully, there was only one product I needed to alter!
