A cookie shop sells 7 different flavors of cookies and 4 different types of milk. Charlie and Delta decide to purchase some products. Since Charlie is picky, he will not order more than 1 of the same flavor. Delta, on the other hand, will only order cookies and is willing to have repeats of flavors. How many ways could they have left the store with 4 products collectively? (For instance, Charlie might purchase 1 packet of chocolate chip cookies and 1 bottle of almond milk, while Delta purchases 2 packets of peanut butter cookies).
