I am a bit disgruntled by this. I bought series 21 when it first appeared on the store a couple of days ago. When I tried to access the episodes the series strangely disappeared from the store. Apple refunded my money and now the series appears again at an inflated price. This is not the first time I have encountered this practice on the store and it is shameful. Apple has informed me that this is the content providers fault. Regardless this is a shameful practice.
