Expedia - things I should know before signing up

Expedia is pushing for more listings in Costa Rica and currently there are not so many listings in my particular area. So I am thinking about signing up.

So I’d like to ask about what you wish someone would have told you before signing up, what to look out for, any experiences …
the food and the bad and your 7 (:wink:) cents.

Also if they give coupon codes to hosts if you refer somebody, I’ll be happy to use one.
