You will find "Available Pieces" on an item's page, this shows the number of pieces the seller is selling.
If the amount is "0" then a "request re-stock" button will appear instead of the "Add to bag" button.
If there is no stock for the item you desire to purchase, please press the "request re-stock" button to send an inquiry to the seller directly about the possibility of purchasing this item for you.
Sometimes sellers have the item on stock already, while sometimes they will retrieve the item for the customer after the order has been placed. Therefore, "Available Pieces" may reflect either of these situations, so it is recommended that the Member messages the seller before submitting order to double check on item availability.
