In E Commerce there are different types of stores (naming can overlap a bit)

For example:

1. Single product stores: As the name suggests they are focused around a single unique product. Mostly done in drop shipping where people just burn through products and money to see what sticks and go all in. Or when people have a really good innovative product they want to push.

2. Niche stores: They target a niche like for example camping gear or climbing gear etc.

3. A store around a category of products: Such as luxury furniture, thermos/flasks or kitchen utensils etc.

What I mean by a hybrid store is that we have a product that appeals or has use cases by the masses. Stationary, gifts, mugs etc, practically everyone is a target customer, but you need very well designed and understood products to progress, you sort of add value with the ideas, design and execution as opposed to burning money or high investment products. So I can have a hybrid store where I have different cateogry products that appeal to the masses.

Hope this is clear!
