A lot of times retailers run sales that exclude certain brands but have notes that say call for deals we cannot advertise.. sometimes it is in you benefit to make the phone call i have lucked out a couple times with some awesome customer service people.
The Tatulas are priced cheaper around in part because of their proposed high margins. One of the reps was talking about it in one of their preview videos leading up its release. It seems like it is working out well for them and the end user because if they are making more money on high sales numbers and the retailers are still making somewhat of a profit giving customers a sale. I believe it is called marginal utility theory if my college econ is still embedded in my head somewhere lol.
