Gotcha. Didn't take into consideration I was paying the closing fees as well. If you made all of the fees visible/obvious it would probably help! When it says a channel is 5k sats and then the bill comes up and its 15k sats its kind of like "huh?" (I still bought a channel)

You're right, however, both the current opening and closing fees are shown at the bottom of the web app.
