**deleteInventoryItem** is not actually deleting items on eBay. I tried many times but **getInventoryItems** always give me 191 items. When I iterated to delete items **deleteInventoryItem** responded two http codes: 404 and 204. I understand 404 means the sku is not found and 204 means deletion success. But when I **getInventoryItems** I still have 191 items and I can still delete the deleted items again and again using the same sku.
