I was delighted to find Diana Krall "Live in Paris" at Costco for $12.99. This stunning DVD is a must-have, and, at that price, buy two in case you wear one out from repeated playing!
I paid $19.99 at FYE (one of the TransWorld subsidiaries).
Anyone who CAN should jump on that CostCo price. This is one excellent DVD (artist, performance, audio & video quality, and technical direction).
