This field is conditionally required if the MaximumItemRequirements container is used.
The value of this field specifies the maximum quantity of an order line item that a prospective buyer may purchase from the seller during any given 10-day period. The prospective buyer will be blocked from bidding/buying once this value is reached.
Valid values for the US site: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 25, 50, 75, and 100.
To see the valid values for your site, call GeteBayDetails with DetailName set to BuyerRequirementDetails, and then look for the BuyerRequirementDetails.MaximumItemRequirements.MaximumItemCount fields.
If the MaximumItemRequirements.MinimumFeedbackScore field is also specified, the MaximumItemCount limit will only apply to those prospective buyers who don't meet the specified Minimum Feedback Score threshold.
See the Field Index
to learn which calls use MaximumItemCount.
