I wouldn't see that as much of an issue, and I wouldn't see free samples as much of an issue either, really.
I'm thinking more along the lines of banner ads not related to any particular juice.
It is human nature for a person to be tempted to provide good reviews of products that people are paying them to review.
And that is essentially what a banner ad is.
If chefjosh can maintain his integrity, that's great.
And if his reviews of juice from those who advertise on his website are fair and balanced that's great too.
And if the vendors that get negative reviews decide to pull their advertising, I doubt anyone would be surprised.
If there are banner ads on the website, and no bad reviews of juices from that vendor, I'll remove the site from my bookmarks.
And life will go on, and everybody will be happy.
Anyway, feedback was requested, and I gave mine.
