Why Price Comparison Matters in Singapore

Price differences between merchants for the same product can be significant:

• Electronics: SGD 50–300 variance (e.g., iPhone 15 Pro: SGD 1,449 on Shopee vs SGD 1,649 at Apple Store)
• Home Appliances: SGD 100–400 variance (e.g., Dyson V15: SGD 799 on Shopee vs SGD 999 at Dyson Store)
• Fashion: SGD 20–80 variance depending on platform promotions
• Groceries: SGD 5–15 variance on identical items between FairPrice, RedMart, and Amazon Fresh

How to Compare Prices: Traditional vs AI-Powered

Traditional Method

2. Search for the product
3. Note the price, shipping cost, and availability
4. Repeat for every merchant
5. Factor in vouchers, cashback, and promotions

Time required: 15–30 minutes per product, easily outdated.
