This one has saved me a few times. It's rare, but every now and then I'll pick up one of those "get around to it eventually titles", unsure if I'd already gotten to it or not.

Nope. Although recently I forgot what Bond movies have and have not been released when I was looking at the single releases at Target.

Never, but I've come close a few times. Not even because I thought, "Hey, I might already have this..." but rather, "Well... I'll hold off. Maybe it'll get cheaper..." and then a week or two later, when browsing my collection, there it is... purchased many months ago.

So, now I've installed the blu-ray.com app. I'm going to try it out this weekend. Can you just scan the barcodes or do you have to enter each title manually?

You can scan the barcodes. If you had to enter each title manually, I don't think I would be using the app.

I've never done it but I've come close a few times where I've had to stop in the store and think real hard about whether I own a Blu of that movie yet or not.

I was looking over my collection the other day and was surprised that I own The DaVinci Code. When the hell did I buy that?!

yes, I thought I had loaned out a Kill Bill 1 & 2 Double Feature, so I bought another one for $15, but soon found it had simply slid to the back of the shelf behind other discs.

Nope, although I have come close a few times, I think, and that's with only ~420 of them.

Pretty cool that you had DVDs in 1996. Must be an insider!

I just did it last week, could've sworn I had'nt upgraded my dvd of The Good, The Bad, and the Ugly to blu, so I bought it, took it home and there it was on my shelf...

I havent had the free time to go through my list to update everything either

No but sometimes I have a hard time remembering what I have, after DVD and HD-DVD purchases.

. I bought a few hundred at Blockbuster for .99 during Memorial Day '11 and have accidentally rebought a couple of those, but nothing I else I can remember.

I just realized I had 2 copies of Snow White and the Seven Dwarfs on Blu-ray. Oops.

I haven't bought any duplicate blus yet. I've bought a few duplicate DVDs (probably half a dozen or so over the past decade). And recently I bought a bluray of a title that I didn't realize I had on DVD.

Not bad given the fact that I'm still just relying on my memory.

I bought a copy of "Spinal Tap" last year, brought it home and stuck it on the shelf...and then stopped when I realized I was putting it beside a copy of..."Spinal Tap." That was the only time though and fortunately I hadn't opened it yet.

Nope.

Not yet. Not quite the same, but I've recorded so many films on my DVR during free preview weekends and such that I've clicked on something only to see a message about "it already existing" in my recordings.

well...i did it again. bought Swingers for $5.00 @ Target and sure enough...already in my collection. i swear i am not this bad!

Just spotted one last night. I bought The Last House on the Left when it was a Best Buy exclusive and again from Amazon. I only know where one copy is.

Really not surprising considering how frequently you post in the "The Last Blu-ray you bought..." thread.

I've done it dozens of times. But since I usually pay so little I just chalk them up as gifts or trade material.

Do you have the blu-ray.com app for the iPhone?

no, but i have my collection on my phone. just didn't think to check it as i thought i was sure i never bought it before. oh well. only $5.00. i'll give it as a gift.

It has happened 4ish times (3 DVDs 1 BR)

Most recently, today, I rebought the Shriek Show Jungle Girls 3 pack. It was in 3 individual cases in a slip cover the first time I bought it, now all three are in 1 case. But it was only $4 so I think I will make it a gift.

My one Blu-Ray blunder was I Love You Man. Bought it the last U&S sale and the U&S sale before that! Still in the 'to watch' pile is why it hadn't clicked in my brain. For $5 I will gift it as well.

Document Of The Dead individual release forgetting it was in the Dawn Of The Dead Ultimate Edition. Sort of justifiable as it includes a commentary not present in the Ultimate edition.

And the first time was a Stan Lee Marvel thing not remembering it was included in the Limited Edition Spiderman box set.

Not in ages because I buy so few now but it has happened in the past when I would pick up tons of DVD's

Doesn't really happen. I keep a very up to date DVDProfiler set up. I also keep a txt file of my collection, noting what occasion I got the dvd or blu-ray for (birthday, christmas, etc.) The only time i buy a second copy of a movie is if I have the movie and it's also included on a multi-movie pack. For instance, I had the Thunderbirds movie. I bought a 4 movie set that had Thunderbirds in it. No big deal. And I had the trilogy set of the Back To The Future movies, but I, knowingly, bought the special edition release of the first movie so I could get the rid footage and the Leslie Nielsen special.
