If my customer orders a certain color of a certain item do I offer a random selection or fill the order just as inputted?

The customer usually knows what they want, you can upsell but never make them question their purchases.

The order put in will be what is packed.  If a customer puts in an order of say a large amount of 1 color, but we offer many, it might be wise to ask the customer if they meant all one color or if they would like a random pack.
