How do I stop the auto pay feature when I buy?

Many times I want to make multiple purchases from same seller over a couple of hours but auto-pay makes combined shipping difficult.

There is no way for a buyer to turn off the auto pay since this is a seller option.  All you can do is ask the seller to turn off the option.  They are not required to do this as it affects all of their listings.
