If you use Click and buy, fill it with the exact funds in 5$ increments first so you have control of what it pulls and when from your bank account.

Click n buy will pull the money from your account if you don't, example:

Your C&B balance is under 7$ and you try to buy 10$ worth of Crysta, knowing it will just pull the remainder from your bank account [C&B tells you it is going to do this right before it does].
