⚠️ Action Required: Wormer - Large Dogs
This is the only SKU where the new COGS has pushed net contribution below 10%, now sitting at 7.1% ($1.35/unit). The July 2026 COGS increase has had a disproportionate impact here because the retail price increase applied (just +5.2%, from $19.95 to $20.99) was the smallest in the range.
A move to $21.99 (the target push price already identified) would recover approximately 3.5pp, bringing net contribution to ~10.7%. This should be the next pricing action.

✅ Key Takeaway
- The July 2026 COGS update reduces net contribution by an average of 2.5 percentage points across the range - a real but manageable impact.
- 10 out of 12 SKUs remain at or above 10% net contribution after the new COGS is applied.
- Crucially, the retail price increases made over the last four months have absorbed the majority of this cost increase. At original prices, 4 SKUs would now be loss-making.
- The only SKU requiring immediate action is Wormer - Large Dogs. A price move to $21.99 is already planned and should be prioritised.

New Cost of Goods - Impact on Amazon Australia Net Contribution
Following the July 2026 COGS update, we have completed a full review of net contribution across the Bob Martin AU range. The headline finding is encouraging: 10 out of 12 SKUs remain at or above 10% net contribution after the updated cost of goods are applied, with the range average moving from 18.9% to 16.4%.
The impact is real but modest - an average reduction of 2.5 percentage points - and this is largely a result of proactive retail price management over the last four months. Across the core range, prices have been increased by an average of 17.3% since the start of the year. This work has been essential: had prices remained at their original levels, four SKUs (Wormer Small Dogs, Flea Spray, Flea Shampoo, and Spot On Cats >4kg) would now be generating a loss after the new COGS is applied.
The one area that requires attention is Wormer - Large Dogs. The combination of a smaller price increase applied to this SKU (+5.2%) and a meaningful COGS uplift has resulted in a net contribution of just 7.1% ($1.35 per unit). A move to the target push price of $21.99 would recover approximately 3–4 percentage points and should be the next pricing action taken.
All other SKUs are performing within acceptable parameters. The Citronella range continues to lead the portfolio with net contributions of 27–31%, and the Spot On range for dogs is well-positioned at approximately 20–26%.
