Input: Text: so i found this out today, painfully. we were having a movie day at work today and i brought my computer and some discs. i told my co-workers that i have nearly a hundred movies and i tend to buy the bluray/dvd combo so i can still watch with dvd when a bluray player isn't available.

well when we also looked over my itunes movies, my co-worker asked me where were all of my movies. when i reminded her that i got blu-ray/dvd *discs* she asked if they came with the digital redemption insert that says you can download them on ultraviolet (which i don't like to use). i said yes, and then she pointed out that many of them also allow you to redeem on itunes. 

i had been throwing away those inserts for years without a second thought because i really hated ultraviolet. i feel so fucking stupid now.

and sure enough, a movie i ordered came in the mail, and the insert confirmed i could also redeem on itunes. the only thing that makes me feel better is that another one of the movies i ordered did not allow itunes redemption. so maybe i didn't throw away so many itunes redeemable movies as i thought.

so, thanks for reading my tifu. ~~here's the ultraviolet redemption for the iron giant signature collection (i still refuse to use ultraviolet/vudu or any of the other retailers) i'll take it off soon as someone confirms they've redeemed it:~~

TIFU by throwing away dozens of movies.
