Having difficulty scraping pricing information from cell phone provider

Hello,

I am trying to scrap pricing and related plan (term) information for cell phones from a provider in Canada. I have started my search (my starting URL) right at the page where the devices are listed. It would seem as simple as creating a link selector that will click on each device, and then text selectors for title, price, and term, but I am not always receiving pricing or term information.

Am I missing something basic? TIA!
