I'm sure I've answered this before in another thread so I have no idea why I'm doing this:

SW VHS (orig. CBS/Fox release in drawer-type box) around 1984-ish (gift from Mom)
ESB VHS (orig. CBS/Fox release) around 1985-ish (gift from Mom)
ROTJ VHS (orig. CBS/Fox release) around 1986-ish (bought used for $30 at mall video store)

"FACES" Trilogy VHS boxed set P&S 1995
"FACES" Trilogy VHS boxed set letterbox 1995
"Hologram" VHS letterbox set 1995

"FACES" LD Trilogy (set one) titles purchased individually from Columbia House - 1997
"FACES" LD Trilogy (set 2-backup set) titles purchased individually from Columbia House - 1997
Special Edition LD trilogy boxed set (bought new from Columbia House) 1999-ish

Definitive Collection Trilogy LD set (bought used from eBay)
SW - 8mm color/sound reel (bought used from eBay)

DVD 4-disc Trilogy SE set 2004
DVD 6-disc Trilogy SE/OOT set in Best Buy Tin 2006
DVD 6-disc Trilogy SE/OOT backup set (titles purchased individually from Amazon) 2006

I've sold everything except the hologram VHS set, the 8mm, all the LDs and the DVDs (and I still have the original SW CBS/Fox VHS box, but the tape isn't original). I've never bought any of the Prequels on video, but my Aunt gave me TPM on letterboxed VHS in a deluxe box with a film cel, but I returned it to Best Buy unopened.
