How IslandDealz picks deals

IslandDealz compares today's price with the "typical price" it has recorded itself, every day — not the full price a shop sets. That catches the trick of raising a price before a sale and "discounting" it back.

Where the data comes from

Prices come from the product file Shopee provides to Affiliate members, refreshed once a day. IslandDealz stores the price of every size and flavour, so price per kg, per litre or per 100 g is right for the exact pack.

The rules

• At least 14 days of data before any verdict
• "Typical price" = the median over the last 14–30 days of data, not the average, so one big sale day can't skew it
• A "deal" is at least 15% below the typical price and the lowest IslandDealz has recorded
• Units sold, ratings and shop type are shown as numbers for you to judge — IslandDealz doesn't use them to hide products
• The commission IslandDealz earns can only break an exact tie between two deals

Verdict labels

• Collecting data — less than 14 days of history, no verdict yet
• Buy now (says Jiw) — a real deal, and past sale days were never cheaper
• Can wait (says Richie) — a good price, but past sale days were cheaper and the next sale is close
• Normal price — close to typical; fine if you've run out, no need to rush
• Not worth it yet (says Richie) — above the typical price

What IslandDealz doesn't know yet

• Shipping, which depends on your address — so IslandDealz shows two backup shops in case shipping is expensive
• Your personal vouchers and Shopee coins
• Price changes during the day — the site updates once a day, so check the price on Shopee before you buy
