MANY STORES DISCOUNT heavily in March to make room for the April introductions. Lots of sales to coordinate with college basketball's "MARCH MADNESS" tournament.

Also, check out the Presidents Day sales (weekend of Feb. 16-19th.)

I don't know about Best Buy pricing, but we have some BBY folks on this forum that can probably answer your question.

In regards to the plasma maintenance question, I'm clueless.

Good shopping, river.
