preorder confusion

Okay, I'm not really bright when it comes to how much a pre order is after i downloaded the tracks that were released prior to the album's release and I'm really confused as to how much it is.

there are 16 tracks (it's a bonus track version) and it was only $11.99 before i downloaded the 5 tracks that are available right now.

I don't know how much it costs now, and I'm afraid I won't have enough.

I only have $10.81 on my account right now and not knowing if I have enough is gonna bother me until the album comes out on the 22nd.

it's 5 seconds of summer's debut album btw if that helps.

I just really need to know because I'm honestly so confused lol.
