Cool 1 gal. short on coolant. Aftermarket coolant or distilled water?

So I was performing the coolant replacement on my 07 WRX, and I didn't realize that the OEM Subaru Coolant came in 1 gallon packs, so I am now about 1 gallon short. It is Sunday and I need to be able to use my car to work tomorrow. What is my best option?

option a) buy another brand of coolant (thinking it's risky) OR

option b) just add a gallon of distilled water into the radiator.

By the way, I am in Florida, and I used the PREDILLUTED OEM coolant, so there is no snow or super cold weather to worry about. I personally think adding another kind of coolant on top of the OEM one is not a great idea. Can I just use tap water until I get more coolant? Gracias amigos!
