The tension in August
The August account snapshot shows $2,008.91 of spend for $3,667.05 of ad-attributed sales. At 54.78% ACOS, more than half the attributed sales value was being spent on ads. The 145-order figure helps ground the story beyond revenue alone.
A very different September
A month later, the visible spend was slightly lower at $1,938.55, while ad-attributed sales reached $8,812.85 and orders reached 217. Sales were 140.3% higher, spend 3.5% lower, and ACOS 32.78 percentage points lower. These are adjacent monthly outcomes—not proof of which campaign change caused them.

What a deeper audit would check
Amazon defines ACOS as spend divided by attributed sales. To understand the mechanism behind this shift, the next layer would be search-term, targeting, placement and advertised-product reports, checked against margin, stock and Featured Offer eligibility. Those details are not visible in the two images.
