Anyone a Google Checkout Expert?

<p>We have been using Google Checkout as an option for the agents in our real estate office to charge the office expenses they accrue. Most pay by check but we like giving them an affordable option to use a credit card. I created a menu of options and charge the agents credit card when they tell me. Occasionally, there are individual expenses that are not a set amount they would like us to charge to their card. Is there a way for me to enter the amount I want to charge and not use the menu I have set up? I am having a hard time trying to figure out the best way to ask my question on the Google Merchant Forum.</p>

<p>Any help is appreciated!</p>
