This plugin round the points on the displayed cart notice… You can't apply in cents… You can only tune in the plugin settings the "Earn Points Rounding Mode" and the best round mode is: "Round to nearest integer"…
What you can do is to fix a minimal number of points to get the discount and display the related notice with the folowing code (Fixed to 100 points below):
// Points and rewards conditional redeem points message display up to 100 points
add_filter( 'wc_points_rewards_redeem_points_message', 'conditional_redeem_points_message', 10, 2 );
function conditional_redeem_points_message( $message, $discount_available ){
$points = WC_Points_Rewards_Manager::calculate_points_for_discount( $discount_available );
if( $points >= 100 )
return $message;
else
return '';
}
And in the plugin settings you will Fix the same number for "Maximum Points Discount".
So the notice will be displayed only for this minimal number of points and the available cart discount will be a real corresponding integer amount…
I haven't find already another way.
