In case any value of a product covered by a rule action is modified manually in Shopify, the modified value will remain valid until the rule ends.

If the rule has not started and the manual change is made, once it starts, it will be changed as set in the rule and when it ends it will revert to the initial value, which in this case is the one set manually.

If the rule is already applied when the change is made, it will revert to the original value detected when the rule was created.
