They don't go on sale.
They WERE prices at 119.00 at one point. Then they dropped to 109, then $99.00
This is the lowest they have ever been, and I highly doubt they'll go any lower. I own three, and picked up two for the convention to use.
Hands down these are awesome.
The best cases for showcasing loose Joes was the BERTBY cases.
They cost $159.00 and would hold 290 CDs, 140 DVDs or 70 videos.
Done correctly, you can get at least 20 figures to a shelf, and about 200 figures in an entire unit.
Sadly, I think IKEA has discontinued them.
