When a product was available before as used product in the past, and now it's not available used anymore, a price update article was generated on every feed loading, because the old used price was still stored in the cache, and therefore different as "no price". The issue was also present in the cas of a New product price that becomes unavailable. Now, when either there is no New or Used price available, the previous price is delete from the cache.
