@elanpro43 It’s not my money or time, so go for it.
diapers.com started in 2005 and dissolved in 2017 so it’s a pretty poor comparison.
The more meaningful point is they opened when amazon was not nearly as big as today. Meaning that competing with them was a possibility back then.
As you can tell amazon has grown tremendously in the same period and has crushed many others in that time. Amazon had a market cap back then of under $20billion, as of today they are $657.15b. Or about 30x bigger than in mid 2000s.
That said, your better trying to make pet food and selling it on amazon. But if a small margin and running around all day for it gets you out of bed in the morning then all I can say is good luck.
