Other than business name, all other fields are required I believe (even if not marked). When I sent in my request Mike called me a little over 48 hours later to confirm and let me know the reason behind the delay. I don't know if calling everyone who requests samples is something they do, or if he just so happened to be the one checking my request that day, but the business name is the only thing I left out.
The reasoning for this, in my eyes, would be to make sure you're not just the same person over and over making requests to get everything for free without paying. Not saying that's what anyone here would do, but not everyone is honest and they're in it to make money, not lose on those that use free e-mails left and right to grab whatever they can for nothing

.
That said,
Aurora-Oblivion, if you can shoot me your First Name and Last Initial via PM, I'll be happy to get in touch with Mike and see if there was an issue. I hope that isn't against the rules here (I didn't see anything about it). Just trying to help so you can enjoy what others are too!
In regards to FlavorWest, he assured me that they didn't buy from them, though that doesn't mean they don't use the same manufacturer that they do. He didn't say much more other than that they were direct and that they had control over their flavors, so if there's something wrong, they can work with the manufacturer to fix the issue.
Once I receive the samples I'll be able to confirm a little more without assuming

. Name wise, I agree, they are the same for many of the flavors. I'll know for sure in the upcoming days.
