Had Eric of ericstrains.com not done such a great job with his train reviews starting a few years ago... this would have been an excellent way for a dealer to stand out from the pack -- reviewing (and subtly promoting ) newly released products. People don't always like to be "sold to" directly, but when sellers provide TRUE added-value to the cause, they build a following of sorts which could eventually lead to increased sales and revenue.
I recall Legacy Station often being mentioned as a "sponsor" of ericstrains.com videos, and I wouldn't at all be surprised if that garnered them some extra business over time (which hopefully sent Eric a few discount dollars toward his next purchases as added "good will"). Audience reach is everything on the Internet , and Eric certainly seems to have a strong, well-earned following.
I've noticed a couple isolated instances where a dealer or two may produce a video highlighting new products in-house, but as things go in advertising... consistency and well-paced regular productions are important when making connections with potential buyers. As folks find increased value in these productions, they may be more inclined to send $$$ your way for that next purchase.
