I actually think they fixed the online version since the last time I checked - when I visited it 3 weeks ago, I remember the site staying on the "walgreens.jobs" domain for the entire visit - now it redirects to jobs.walgreens.com. I wonder if they were using an old poster from before the law came into effect, and maybe even the listings/website were old before the migration to jobs.walgreens.com - now they do include a link to the pay information, but I love how they make you copy and paste a URL instead of just directly including the info, or even making it a hyperlink.
I found the a job listing in boulder here, which has the same pay range link as above:
https://jobs.walgreens.com/en/job/boulder/pharmacy-technicia...
But yes, per CO law, the job posting you took a picture of should also state the same pay range and benefit info (page 4).
