1: The marketing mix id B2B, the magazines, the store's website, and Amazon. The 4 p's would be first, the garment itself, then $45 and $75, place- their website and Amazon, and promotion- B2B and magazines.
2: The consumer market would be the 4 p's that consumers can access and consume, so the same as the organizational market.
3: The customer profile for the organizational market would be the advertisers they are trying to attract I think.
4: The customer profile would be the young men that they are marketing to in their promotion.
5: The market share is the whole of their personal website, most of their niche in B2B, and a small part of the magazines and Amazon.
I am fairly new to this subject, so my answers might be incorrect, but they are my best shot. Good luck!
