If it's anything like the non-profit space, the multipage checkout, if done right, can allow you to psychologically hook the donor in and yield higher completion rates. (Clicking a donation option is much lower commitment than typing your name and address as a starting point.) It also allows you vary the checkout steps based on what the donor selects. You can then treat a $10 differently than a $500 donor to optimize conversion rates for each cohort.
