Picos are cheap, so you can probably tell the truth in this case. Just omit the Bridge price from that conversation.
Button Controller works good, but don't forget that you can use Rule Machine and Simple Automations too depending upon what you are trying to do. Tons of creative uses for Picos.
And for the cleanest and easiest button controller app, try Advanced Button Controller. I have moved all but one thing from the Hubitat native Button Controller into this one.
