Is Google Fi particularly cheap? Their normal prices seem to start at $35/month for 30GB of data which is more than Verizon's Visible plans at $25/month. (The current 50% off offer on Google Fi does seem a good deal though.)
I ended up switching to Mobile-X since I'm on wifi so much I only use a few gigs of data a month. $2/month + $1.90/GB vs Google Fi's flexible plan of $20/month + $10/GB.
My Google Fi is $20/m for connectivity and then $0.01/Mb until I hit 6Gb ($80) at which point everything after is no cost. Most of my data is on wifi, so my bill rarely goes above $25

If you travel internationally, they're really cheap relative to everyone else who will charge you absolutely ridiculous roaming fees.
