Free shipping is available with a minimum order of $150 after discounts. Otherwise, we charge a flat delivery fee of $12 islandwide, and a minimum spend of $30 is required to place an order.

This small delivery fee allows us to keep our product prices as low and accessible as possible — without compromising on quality.

On public holidays a $20 surcharge applies to help cover additional operating costs. Any applicable surcharges will be clearly shown at checkout.

Yes — You can schedule your delivery in 2-hour blocks on weekdays:
10am–12pm, 12pm–2pm, 2pm–4pm, 4pm–6pm, or 6pm–8pm.

We’ll do our best to deliver within your selected window, but as deliveries are routed based on the day’s orders, slight variations may occur.

On weekends, we’re currently unable to offer time slot selection — all deliveries will be made between 12pm to 5pm.

Same-day delivery is available on weekdays, at no additional charge. Just place your order early — we’ll need at least 1 hour of lead time (e.g., order by 9am for a 10am–12pm slot).

Planning ahead? You can place your order up to 1 month in advance. For seasonal items like uni, prices fluctuate weekly — so these may only be available closer to your selected date.

If you’re not home during delivery, we’ll leave your items safely at your doorstep.
