April retail sales came in at $757 billion according to Census Bureau data — roughly flat with March, up modestly year-over-year. Consumers are still spending. Whether that spending is generating the parcel volume DSP operators need is a different question.
E-commerce held approximately 16% of total retail in Q1 2026, a share that's been broadly stable since the post-pandemic surge normalized. Parcel demand isn't collapsing — but it's not growing at the rates that justified aggressive DSP fleet expansion in 2021–2022. The operators who built for 15% annual volume growth are now managing fixed costs against a market that's growing at 4–6%.
The mix shift is the more immediate pressure. Consumer spending has rotated toward lower-ticket, higher-frequency online orders — household consumables, pet supplies, personal care — at the expense of big-ticket electronics and furniture. More stops per route, smaller packages, similar or lower rate-per-stop. That's an efficiency story, not a volume story, and it squeezes operators who haven't tightened their cost-per-stop math.
Amazon continues expanding its delivery station network in suburban markets previously served by USPS or UPS SurePost. More stations create more DSP route slots — but also tighter density requirements and more competitive scoring on delivery performance. Volume is available for operators who perform; it concentrates away from those who don't.
The practical read for DSPs on current market conditions: plan for volume that grows slowly or holds flat through 2026. The operators surviving the margin pressure of this period are running tighter numbers — cost per stop broken down to component level, route efficiency tracked weekly, van utilization above 85%.
Stable retail sales are a floor, not a growth engine. Build the operation around the floor.
