If you don’t mind me asking, what are the e-commerce sites? Also, how does one get into such a business? Were you interested in this space beforehand or did you simply acquire a business that looked promising?
In my personal interactions with people in the e-commerce/drop shipping space, the odds of them telling you what they sell is extremely slim. The barrier to entry for anyone else is very low, so once someone has a winning product, they remain very tight lipped about what exactly it is.
Seconding the interest in this. Some research showed that SoulCeramics and ZenConcessions are two of the commenter's businesses, but I would love to hear details on how he found them, decided to buy them, and then dealt with operating them. Selling popcorn machines and pottery kilns, such fascinating niches to become wealthy off of.
Unfortunately, he won't tell you, because like someone else said, the barrier to entry is so low, that their only real competitive advantage is other people not knowing about the opportunity.
