I cant go into detail much because itd make it easy to google my place of employment.

We pay for trips, electronics, "lab kits", license fees, PPE, raw materials, rental fees for heavy equipment and due to the nature of the content we pay probably more than we should due to inflated costs related to the specialized nature of the topic and school contracts.

AND we pay sales tax on all of it, which isnt insignificant on already ridiculous costs.
