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

1. Visit each merchant website individually
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Time required: 15–30 minutes per product, easily outdated.
