Side projects that are making money, but you'd not talk about them?

I love how thoroughly they asked about the dog food business on this.

Most profitable online stores are not willing to talk about themselves. Coz they are afraid of being copied with a low entry barrier, especially for the dropshippers. The only protection is the niche they pick, which is the secret they won't tell the others.

Reselling stupid non sense on eBay, including a bit of drop-shipping.

I randomly started selling items with a 100% margin or more, items that anyone could easily find at the price I'm getting them at. Not buying in bulk to resell in smaller quantities.

I never felt good about it, so never really tell people I was doing this.
I guess I never dedicated a lot of time to it to grow it and make it be a serious source of income. It adds no value, except perhaps some convenience to consumers who seem to only know eBay and Amazon to buy stuff online.
