Prime Day 2026 Opens a Back-to-School Stock-Up Window for Kids' Socks
Key facts
A 2024 survey of more than 1,000 U.S. parents, conducted by commercial real estate firm JLL and reported by Retail Dive, found that families planning back-to-school purchases intended to shop most at Walmart (46.4%), Amazon (35.4%), and Target (32.6%). A February 2026 market analysis from Mordor Intelligence found that online sales in children's wear are growing at a 7.42% compound annual rate through 2031, outpacing the overall children's wear category's 5.92% annual growth rate. Physical stores still held 81.9% of the children's wear market as of 2025, but that share is declining.
- Walmart leads back-to-school purchase intent at 46.4%, followed by Amazon at 35.4% and Target at 32.6%, per the JLL survey of 1,026 parents.
- Online children's wear is projected to grow 7.42% annually through 2031, vs. 5.92% for the overall market (Mordor Intelligence, 2026).
- More than 83% of all U.S. retail sales still occurred in person as of Q3 2025, according to St. Louis Federal Reserve FRED database data.
What it means for parents
Parents buying replenishable basics, the socks, underwear, and undershirts that children go through quickly, face a genuine channel decision in 2026. Big-box stores like Walmart and Target offer grab-and-go simplicity during an existing grocery run. Walmart in particular dominates back-to-school spending intent, and its everyday pricing on name-brand multipacks is hard to beat for an unplanned restock.
But when a family is making a deliberate decision, restocking a full drawer after a growth spurt, or buying enough socks to cover a school year, online multi-pack formats often produce a lower per-item cost and zero travel time. Amazon's Subscribe and Save program compounds this advantage: families subscribing to five or more recurring items receive up to 15% off per delivery, and the schedule is adjustable. For socks replaced two or three times a year across two children, the savings over a year of school can be meaningful.
Background and context
The competition between these two channels is sharper in 2026 than in any prior year. Retail Dive's January 2026 analysis of industry trends noted that big-box retailers, Walmart especially, have invested heavily in same-day and sub-three-hour delivery to close the convenience gap that historically pushed replenishable purchases online. Amazon, meanwhile, delivered 6.7 billion U.S. packages in 2025, edging past the Postal Service in volume for the first time, according to shipping analytics firm ShipMatrix, and has been expanding same-day delivery into grocery and household categories.
Despite that momentum, physical stores hold substantial ground. More than 83% of U.S. retail sales still occurred in person as of Q3 2025, per St. Louis Federal Reserve data. A Forrester forecast cited by Retail Dive in early 2026 projected that over 70% of retail sales would still come from stores through the year, even as online growth rates outpace in-store gains. For children's wear, the most durable shift is in the consumable sub-segment: basics like socks and underwear are moving online faster than fashion items or outerwear, largely because the purchase is planned and repetitive rather than exploratory.
Tariff pressure on apparel manufactured in Asia has added a cost-consciousness layer to this shift. Circana's chief retail industry advisor noted in late 2025 that fast-cycle categories, including children's clothing, were among the first to absorb new import costs. Buying a 10-pack at a time, rather than replacing two pairs at the checkout lane, is one concrete way families stretch their per-item budget when prices are moving upward.
Takeaway
For most U.S. families in 2026, buying kids' basics is a split decision, not an all-or-nothing one. Walmart and Target serve the spontaneous, same-day restock. Amazon serves the deliberate quarterly refresh, where multi-pack value and scheduled delivery reduce both cost and friction. For a category like children's socks, which kids outgrow and wear out on a rolling basis, that combination of convenience and per-pair economics gives online channels a durable edge for families making intentional purchases.

Frequently asked questions
- Is Amazon cheaper than Walmart for kids socks and underwear?
- It depends on how you buy. Walmart generally posts lower single-item everyday prices, but Amazon multi-packs, especially with Subscribe and Save discounts, often produce a lower per-pair cost on replenishable basics like socks. A 2024 JLL survey of more than 1,000 parents found that 35.4% planned back-to-school purchases on Amazon versus 46.4% at Walmart, suggesting both channels have a firm role.
- Why do parents buy kids basics online instead of at a store?
- Convenience and value-pack economics are the main drivers. Multi-packs ordered online eliminate repeated store trips during growth spurts, and doorstep delivery removes the friction of restocking on the fly. Mordor Intelligence's 2026 children's wear report found that the online channel is growing at 7.42% annually, outpacing the overall category's 5.92% rate, which reflects this behavioral shift.
- How do tariffs affect prices on kids' clothing like socks in 2026?
- Tariffs on apparel manufactured in China and other parts of Asia have put upward pressure on fast-cycle basics. Circana's chief retail industry advisor noted in late 2025 that children's clothing was among the first categories to absorb cost increases. Buying multi-packs in quantity, rather than replacing pairs one at a time, is one practical way families can manage per-item costs.
