Please note the 20 July announcement stated that the insertion fee tier for a multiple item listing using the Store Inventory Format was to be determined by multiplying the asking price by quantity of your items.
Upon further analysis we have decided to reverse this decision and in a few months Insertion Fees for Multiple Item Listings will again cover any quantity of items within a single listing in Store Inventory Format. We regret any inconvenience and will be issuing credits for the difference within billing in the interim. Any applicable refund will appear in your regular statement.
