If true, ReduceReserveAllowed indicates that all categories on the site allow the seller to reduce an item's reserve price. If false, this field is not returned in the response and all categories on the site do not normally allow sellers to reduce an item's reserve price. The Category.ORRA (override reduce reserve price) field can override (or toggle) the reserve price reduction setting for a given category. For example, if ReduceReserveAllowed is false and Category.ORRA is true, the category overrides the site setting and supports reducing reserve prices. If ReduceReserveAllowed is true and Category.ORRA is true, the category overrides the site setting and does does not support reducing reserve prices.
