Best Buy - Memorex 20 Pk Cdr $1.99

Best Buy has 20 packs of MEMOREX CDRs. They are 4 each of 5 different colors. The shelf will not have $1.99 but they ring up okay! I bought 10 packs myself. They had various speeds from 24X, to 40X and 48X. I have heard that they also had 16X.
The package says, MEMOREX, COOL COLORS CD-R. (Note they have the CD cases included!

This is in the USA! Not sure when this will end!

Are they supposed to be $1.99? Does it just happen to be an error at your Best Buy?
