DISPATCHWhy Your Best-Selling SKU Is Killing Your Margin
here is a specific kind of operator who has cracked the acquisition code. Their hero SKU converts at 4.2%. Their ROAS holds at 3.8x across Meta and Google. Their Shopify dashboard glows green every morning. And they are quietly bleeding out.
This issue dissects the contribution margin trap — the gap between blended ROAS and the number that actually matters when your 3PL invoice arrives. We pulled the books on seven stores between $80K and $600K monthly revenue. The pattern is identical.
Data drawn from 7 anonymized DTC stores, $80K–$600K MRR. 3PL costs include pick-and-pack, kitting, returns processing. Paid acquisition at blended ROAS 3.1×.

What operators write in the margins
These are the messages that arrive on Monday mornings, after the issue ships on Sunday night. Operators who check dashboards at midnight tend to read newsletters at 6 AM.
“The 3PL cost breakdown in Issue 003 saved us $14K in the next contract negotiation. I printed it out and brought it to the meeting.”
“I've read every DTC newsletter. Dispatch is the only one that doesn't treat me like I need to be convinced that margins matter. It assumes I already know. That's rare.”
“The container rate brief in Issue 005 was more useful than the $4,000 logistics consulting call I had the week before. I'm not joking.”
