Gas prices are up. Yet, brands are still wondering why sales are down. Your COGS

Gas prices are up.
Yet, brands are still wondering why sales are down.
Your COGS go up because it costs more to receive raw materials. Your freight to Amazon goes up because diesel isn't getting cheaper.
Your margins get squeezed from both sides simultaneously.
Companies can't absorb this, and they're not built to.
So prices go up. AGAIN.
If you're an Amazon seller and you haven't modeled out what a 30% freight increase does to your unit economics, do it TODAY.
And if you sell through retail channels alongside Amazon, you already know the rules: raise Walmart and Target prices first. Then Amazon.
Get the sequence wrong, and you lose the Buy Box on top of everything else. This is the second major cost wave hitting Amazon sellers in 2026.
