1. My purchase decision is based on packaging (smaller the better), cost (under $1 is best), and reputation (ie, the gel can't fail me during the marathon).
2. Generally I'll buy whatever known product is cheapest for five bags.
3. I'll buy fresh gel at each expo, so your product would have to be available at one of the expo's booths. Whether or not your product was the marathon gel would not matter to me.
