About
Jia is a Shopping Editor at ShopBack covering consumer pricing, sale cycles, and retailer comparisons across Australia, Singapore, and the United States. The job, day to day, is to figure out whether a given retailer price is genuinely good and to write the answer in a way shoppers can act on. The reporting draws on ShopBack's internal merchant pricing data across thousands of retailers in the three markets, paired with primary sources: retailers' own sale histories, official promotional pages, and government statistics from the ABS, SingStat, and the BLS.
Markets
| Market | Retailers tracked |
|---|---|
| 🇦🇺 Australia | Amazon AU, JB Hi-Fi, Harvey Norman, Officeworks, Big W, Kmart, Coles, Woolworths |
| 🇸🇬 Singapore | Lazada, Shopee, Courts, Best Denki, FairPrice, Cold Storage |
| 🇺🇸 United States | Amazon, Walmart, Target, Best Buy, Costco |
Areas of focus
Sale-cycle timing — Tracking when sales genuinely cut into margin versus when the markdown is theatre. Key windows: EOFY (June, AU), Great Singapore Sale (June–August, SG), 11.11 (SG and AU), Black Friday / Cyber Monday (US, AU, SG), Boxing Day (AU), and the major US weekends around Memorial Day, July 4th, and Labor Day.
Cross-retailer pricing — Same SKU compared across the field in each market. Prices verified at the actual in-cart level, not the advertised banner.
Category playbooks — Sneakers, beauty and skincare, consumer electronics, baby gear, travel, and groceries. Each playbook covers what to pay, when to pay it, and where the resale or open-box market sits twelve months on.
Cashback as a layer — How stacked cashback compares against credit-card rewards, store loyalty programs, and coupon stacking, written region by region.
Editorial standards
Every price reference traces back to a primary source — the retailer's own site, official sale page, government statistics (ABS, SingStat, BLS), or ShopBack's internal merchant pricing data. Coupon aggregators, deal-listing sites, and third-party scrapers are not cited.
Prices are checked against the actual in-cart total during the article's coverage window. Every number gets a date attached. The date_modified field reflects when numbers were last re-verified — at minimum every quarter.
Recommendations are conditional: "best buy" is always stated for a specific reader under specific conditions. Errors are corrected in-article with the date and nature of the change noted. ShopBack earns commission through cashback links; where a merchant pays a notably higher commission than peers, the conflict is disclosed inline. Editorial picks are not sold.
