What is another term for rebates?

The term "rebates" refers to a portion of the purchase price that is returned to the buyer after the sale is completed, usually as an incentive or promotion. The correct choice, which is "after market arrangements," best captures the concept of rebates because it suggests a financial arrangement or adjustment that occurs after the initial sale transaction. This aligns with how rebates function in a market context, where they're often used to adjust pricing in response to market dynamics or customer purchasing behavior.

In contrast, while "discount agreements" may imply a reduction in price offered upfront, it does not encompass the post-sale return characteristic of rebates. "Post-sale returns" typically refer to items being returned for a refund rather than a financial incentive offered after the purchase. "Credit adjustments" might suggest an account-based modification, but it lacks the specificity and market-oriented context that "after market arrangements" provides when discussing rebates.
