In my experience, most pricing "errors" come from the listing owner/creator changing the SKU or quantity set on the listing. When this happens, it takes us a few days to catch up with the listing or remove it entirely if we think it's low quality (meaning we think it's a pack of 100 and it's really a pack of 10). This can become even further complicated when a listing changes right as velocity comes on for it as well. We basically have to forget what the listing did before so we can price it accordingly moving forward. Pricing can also be a direct result of a velocity + stock calculation. If we are running low on FBA stock and don't have a good supply for the item ATM, the system may use a not-so-great source price on the item to calculate what it will cost us to refill stock. Sometimes items move around, or we lose suppliers for items, which cause the system to adjust the price accordingly. If you are searching from Amazon proper (not our store) for those items in question, it is very likely Amazon won't show you our listings on them because of the price delta. I would note we definitely utilize customer feedback to constantly improve our system's accuracy.
