Bests & Worsts Reviews from Amazon

Did they think nobody would notice such a dramatic price change? When I looked this morning, the price for The Day Of The Doctor was $3.99, and the price for An Adventure In Space And Time was $2.99. This afternoon, the former is $7.99 and the latter $6.99. That is exorbitant, firstly, and it also does suggest price gouging. I thought Amazon was better than this -- certainly, they stood to make plenty of money on these episodes at the lower price, and they got greedy. I buy an awful lot on Amazon, but I have to say, this makes me want to take my business elsewhere, and not just for streaming. Christmas is almost here, folks -- do you really want all Whovians to do our holiday shopping elsewhere? (UPDATE: These are the same prices as those currently at the iTunes Store. If Amazon got in trouble for charging too little in this case, a public statement would certainly be appreciated and would alleviate a lot of the ill-will that they've generated here.)
