Can I set a regular monthly credit purchase for any amount?

Yes, as long as you operate within the minimum and maximum credit purchase terms. Credit boosts are awarded based on increments of 20 credits purchased.  For every 20 credits purchased as a part of a regular monthly credit purchase, one credit boost is awarded.   

To qualify for a credit boost you must purchase a minimum of 100 credits every month.  From the widget, you can select from preset options of 100, 500, 1,000 or 2,500 credits (which is the maximum) or select the Custom amount option and enter the exact number of recurring monthly credits required.
