The ability to use up points for part of the value a product in the basket.
 
e.g 1 point = £1
 
Item value is £20
 
Clients has a points balance of 10 points.
 
When applied this reduces the cost of the item to £10
 
+ also to add to this. A "use all points available option"
 
So if the client has 100 points and the order is £120
 
they would click the button " use all points available option" and the order is reduced to £20 i.e
 
The system works down the items in the basket until it runs of of points deducting a part amount off the last item it reduces (or the full amount in rare cases where the value of points exactly matches the value of the some or all goods)
 
Any other backers for this?

Not sure about the 'user all points available' option. But that can't hurt.
 
Most importantly I support the need for the system to allow customers to spend points to part pay for an item.
 
My customers do comment that they would like to be able to do this.
 
I would have thought ViArt would be built with the option... Use points to "pay in full", "pay in part". "both".
