Is AMAZON FBM Worth it? Help

Is fulfilled by me worth it on Amazon? I’m thinking of selling on there but would rather start simple by listing fbm products rather than fba.

I’ve heard you cannot get the buy box under fbm and I am wondering if anyone else has any experience, what have your sales been like?

Many people don’t even realise there are other sellers for certain reselling items and assume it’s only the ‘buy box’ listings.

Even people who do realise (myself included) generally just buy from the buy box than even look at other sellers, especially when most others sell used items.

I will be selling brand new I’m just trying to decide whether or not it is worth it?
