Agreed on the font size, a bit small. I've also seen pricing pages do well when you highlight a suggested package or the "Most Popular"
I think your overall pricing structure and flow need some work. I'd rethink this approach completely with whoever is in charge of PM.
The flow doesn't make any sense, based on your pricing structure (IMHO). For instance, I can add 20 beacons to my cart but select the BASIC nine beacon plan.
Instead, I would lead with the hardware, and suggest the right software package, based on the beacons added to the cart (though I even question the package model you have here). So you would have a two-part flow.
Also, the font is too small in the plans area. Suggest at least 14-15 pt.
Also, fix positioning the checkout button to the bottom of the screen is unconventional, and likely to be missed (I missed it).
Fo me font is too small and hard to read. Also I which images be retina ready http://take.ms/JWRU8
