Six categories switch rate on the whole price at $20: Baby Products (8% at $20 or less, 11% above), Beauty, Health and Personal Care (8%, then 13%), Clothing & Accessories (10%, then 13%), Grocery and Gourmet (8%, then 10%), Pet Products (10%, then 13%) and Tools & Home Improvement (10%, then 13%).
That line is worth checking before you set a price. A $19.95 beauty product pays $1.60 in referral fee; at $21.95 it pays $2.85. For a GST-registered seller the extra $2.00 is worth $1.82 after GST, and $1.26 of it goes to the higher fee — so the price rise nets about 56 cents a unit.
Five categories work the other way, charging a lower rate on the portion above a threshold: Computers (8% up to $150, 6% above), Jewellery (15% up to $200, 5% above), Shoes, Handbags & Sunglasses (14% up to $50, 10% above), Sports and Outdoors (13% up to $200, 12% above) and Watches (12% up to $50, 8% above). An $80 pair of shoes pays 14% on the first $50 and 10% on the other $30: $10.00, or 12.5% overall.
