A cookie shop sells $7$ different cookies and $4$ different types of milk. Gamma and Delta decide to purchase some items. Gamma, who is peculiar about choices, will not order more than 1 of the same type. Delta, on the other hand, will only order cookies, and is fine with having repeats. How many ways could they have left the store with $4$ items collectively? (A possible purchase could be Gamma buying 1 chocolate chip cookie and 1 almond milk while Delta buys 2 oatmeal raisin cookies).
