This is an example of the illogical way the site is programmed. Why bury the information at the bottom of page of the "Payout Methods" (which already takes a couple steps to get to)?
Following this illogic, if I click on "Travel Credits" in the drop-down box under my profile photo, it just comes up with a page about how I can earn travel credits by referring other hosts, etc. Wouldn't you think your travel credits would show up under "Travel Credits"? These programmers are really mentally deranged.
