While they're not bad, in the future it would be cheaper to get standard bulk protein powder and add other stuff as required. Post workout you could add a carb source such as ground oats (very cheap). Eating something right before bed isn't really necessary either, but if you wanted to have something just a standard protein shake would do. Even better, actual food (high in protein and fat, low carbs). In fact, EVEN better would be to skip that pre-bed snack and just eat more during the day.
