Origin
Sam's Club implements a paid membership system starting at 260 yuan paired with bulk-packaging sales. A large number of non-members and single young people want viral roasted chicken and Swiss rolls without wanting to buy a membership card or hoard whole boxes, leading daigous to emerge to fill this demand gap. Daigous monetize through per-item fees, proportional markups, and repackaged retail, gradually forming a complete chain including online purchasing on behalf of others, offline guest-entry assistance, and unboxing/repackaging.
Milestones
2016年
Inception Failure
In 2016, Sam's China had only a dozen or so stores with mediocre customer traffic. Early daigou customer bases were small with low per-customer transaction values, and most part-time daigous making a few hundred yuan a month found it hard to sustain. Stores in Kunming and Changchun had previously transitioned to Walmart hypermarket formats between 2002 and 2004 due to dismal operations, leaving the daigou ecosystem with virtually no soil to grow on.
2019年
Eve of Expansion Turning Point
Sam's accelerated store openings and launched its one-hour flash delivery (JiSuDa). Content about visiting Sam's exploded on Xiaohongshu and Douyin, shifting daigous from small orders among acquaintances in the same city to taking orders on social platforms. Some top-tier daigous began placing steady orders with item markups of 5 to 20 yuan, a phase that lasted from 2019 through 2020.
2021年
Viral Surge PMF
In 2021, Sam's became a newly minted check-in hotspot, with viral roasted chicken, mochi, and Swiss rolls seeing lines and rushed purchases. The daigou repackaging business exploded, with full-time professional queue-waiters and repackaged reselling appearing around single stores. The media publication 'China Foreign Investment' recorded scenes of crowds in front of checkout counters and daigou shopping carts clearing inventory.
2023年
Arbitrage Scaling Growth
By 2023, the daigou supply chain matured: earning price differences by purchasing discounted shopping cards, reselling elite membership cashbacks and bundled perks, and charging 10 to 20 yuan per person to bring cardless consumers into the store. Some professional daigous claimed monthly incomes exceeding 10,000 yuan, spawning specialized daigou communities and order-taking tools.
2024年
Tightened Regulation Transition
Sam's strengthened controls over daigou behavior, limiting single-card purchase quantities and banning abnormal membership accounts. Some stores implemented facial recognition and a one-person-one-card entry policy. A large number of daigous relying on guest entry and bulk cart-clearing were forced to pivot to online proxy ordering or exit the industry, triggering a clear industry reshuffle that lasted through 2025.
2026年
Ongoing Game Turning Point
Against the backdrop of Sam's members exceeding 10.7 million, stores surpassing 60, and plans to open 10 new stores in 2026, the tug-of-war between daigous and official management continues over member benefits and food safety repackaging liabilities. With sales targets set for a 15% comparable store growth, daigous still occupy some non-member consumption gateways, but profit margins continue to be compressed.
Turning Points
- The viral explosion of internet-famous products in 2021 turned daigous from small-scale acquaintance businesses into scaled social platform order-taking operations.
- Starting in 2024, Sam's tightened membership policies and entry controls, severely hitting the guest-entry model.
- Elite membership card rebate and cashback rules became the core profit source and policy game focus for daigou arbitrage.
Failures & Pitfalls
- Early daigous relying on periods of sparse stores mostly exited at a loss due to low ticket sizes and meager demand.
- The per-head fee model for bringing guests into stores nearly failed after Sam's implemented a one-person-one-card policy, forcing a large wave of practitioners to leave.
- Repackaged foods lacked labels and traceability, and multiple food safety disputes pushed repackaging retail toward complaints and legal risks.
关键成功要素
- The membership card threshold itself is the prerequisite for daigous to exist, with price-spread space originating from institutional barriers.
- Viral hit products act as traffic entry points, with single items like roasted chicken and Swiss rolls carrying inherent social propagation attributes.
- Diversified arbitrage points—shopping card price differences, rebates, and perk resales—layer together to create stable cash flow.
- Closely tracking platform policy changes to rapidly switch models is the survival rule for pivoting from guest entry to online proxy ordering.
Lessons
- The ceiling of a parasitic business is determined by its host; a single new platform rule can wipe out an entire model.
- The thicker the profit margin in gray areas, the higher the probability of a concentrated outbreak of compliance risks.
- Repackaging and split-selling bypass the brand's packaging liability system, making food safety a hard risk hanging overhead.
- Arbitraging by attaching to a single channel requires building private-domain customers early on, otherwise there is no backup plan when policies tighten.

Competitors / Peers
The counterweights to daigous are Costco, Hema, and Sam's official flash delivery (JiSuDa). Costco has fewer stores and slow expansion, resulting in a smaller daigou market under the same membership card model; Hema directly dissolves repackaging demand with zero-threshold membership and small-portion fresh produce; while Sam's official platform squeezes daigou space using one-hour flash delivery (JiSuDa) and purchase limits/card bans. This three-way pincer attack leaves daigous fighting for survival only in the gaps between non-members and bulk-packaging repackaging.
