I just want to put "$29 per month" into perspective:

Imagine a white collar employee earning $100K per year. $100K / 250 working days is $400 per day. Payroll tax and benefits can easily add +50% to that, so it's not a stretch to guess that our hypothetical employee costs the employer $600 per day.

$29 per 20 working days is about 1/4 of 1% of that cost.
