I know what you mean:
I went into Best Buy the other day with the plan to buy ONLY the new Elton John Captain Fantastic SACD. Well, I left the store with all 5 Elton SACDs (no Peachtree Road) and all 3 Eric Clapton SACDs. $14.99 each but this discount card I have took $2 off each one so I think it was about $110. Plus I went back the next day for some purchases for the wife: Shania Twain's Greatest Hits and Britney Spears Greatest Hits:My Prerogative on DVD! (of course, I had to watch it too, darn...)
