The problem
FBA isn't always the answer.
FBM often wins for heavy/bulky items, FBA for light fast-movers — but only the numbers can tell you.
📦
Hidden FBM costs
Packaging, labor and returns handling — FBM isn't just postage.
🏬
The FBA fee chain
Fulfillment plus storage fees add up thinner margins than expected.
⚖️
Gut feel vs math
The model choice should come from per-unit net, not gut feel.
