If you want a physical copy of the LOTR trilogy on Blu-ray (not 4K) and aren't looking for the extended versions, Target has the following deal....
$10.99, and another 5% cheaper with RedCard. Normal price is under $17 on amazon and wal-mart. This is 35% off the normal price, and is probably in low demand since it is just the theatrical version in 1080p.
For those of you looking for digital versions/extended cuts/UHD etc., the microsoft store deal from last week is a great FP deal (link below)
