The company
Seven Times Six sells officially licensed pop-culture and fandom merchandise — backpacks, apparel, accessories, and cosplay gear built around properties spanning games, movies, and television — through an extensive online catalog spanning multiple ecommerce platforms.
Where they started
The company ran fulfillment out of a single warehouse in Utah. That worked fine for West Coast customers; for East Coast customers, it meant 5-7 day delivery times — a real disadvantage in a category where other sellers on the same platforms could ship faster. Warehouse costs, labor, and the operational complexity of managing orders arriving from several sales channels at once were climbing as the business grew, with peak season the sharpest pressure point: the company's Marketplace Manager, Samantha, described relying on a large temporary headcount just to get through a single holiday season's order volume.
What they did
- Enrolled in Walmart Fulfillment Services (WFS), moving inventory into Walmart's fulfillment network to get 2-day shipping coverage across the U.S., rather than shipping every order from the single Utah warehouse.
- Adopted Walmart's Multichannel Solutions program, which lets a seller fulfill orders placed on other ecommerce platforms out of the same WFS inventory pool — instead of running a second, separate fulfillment operation for non-Walmart channels.
- Integrated with solution provider Rithum for the API connectivity needed to route those other-platform orders into WFS automatically, rather than re-keying them by hand.
The numbers
Walmart's case study reports a 50% reduction in delivery time to East Coast customers after moving into WFS, more than 3,000 orders shipped through Multichannel Solutions during a single peak season, a 97% average On-Time Delivery rate, and a Valid Tracking Rate above 99%.

Why this worked
Multichannel Solutions is the detail worth noticing here. Adopting a marketplace's own fulfillment service usually only solves shipping for that marketplace's channel and does nothing for the others a seller also runs. The win for Seven Times Six was that the same WFS inventory could absorb order volume from platforms that aren't Walmart at all, through a fairly straightforward Rithum integration, rather than requiring a second, parallel fulfillment relationship for those orders. As Samantha put it in Walmart's case study, that's what let the team avoid needing a much larger seasonal headcount — not just ship a little faster.
What to take from this if you're earlier in this path
If you're already committed to Walmart Marketplace and separately maintaining fulfillment for other channels, it's worth checking whether a marketplace's own fulfillment network — WFS's Multichannel Solutions here, or Amazon's Multi-Channel Fulfillment on the Amazon side — can consolidate that instead of running parallel warehouse relationships. See FBA vs. WFS vs. 3PL: Choosing a Fulfillment Model and Building a Multi-Fulfillment Strategy for how to weigh the trade-offs before committing inventory to one network.
FAQ
Does WFS's Multichannel Solutions only work with Rithum as the connectivity layer? No — Rithum is the specific solution provider Seven Times Six used, but Walmart's Multichannel Solutions program is built to work with multiple approved integration partners. See Choosing a Multichannel Middleware Provider for how to evaluate options before picking one.
