Yes, some of these are cheaper elsewhere online, but for someone wanting local stock, these are decent prices.
Their prices fluctuate waaaay too much. I got the extended Blu-ray trilogy of LOTR 2/3 years ago at JBHIFI for $45-47. I have seen it at the $100 plus mark and anywhere in-between depending on the weather.
I think they jumped the prices up because of the demand after the Hobbit movies were released. Dirty, but $57 isn't TOO bad.
EDIT: Yep, marked down from $114.98. So less 20% it would be $92 approx, so me also thinks those routine 20% off deals are just bringing the price back down to an acceptable level…for them.
Still, $57 is the best I have seen in a brick and mortar store for a long time.
