That's not right really. The buy the singles and re-buy them again when the album becomes avaliable is an old thing, (like in Britney Spears Circus and Gwen Stefani's Sweet Escape) artists don't do that anymore, like Ke$ha, Katy Perry. and now Lady Gaga.
The Born this Way albums already show up in my Complete my album page even when i already bought the full price album because i got desesperated:

I got also the screenshot of the album with the discounted price:

It was just a glitch of iTunes. I also got a response from the Apple iTunes Support people with the email I sent them below their reponse:
Dear Yobyz,
Welcome to iTunes Store Customer Support. My name is *** and I am glad to assist you today.
I'm sorry to hear that you're charged for the price of whole album instead of getting the discounted price.
I have reversed the charge for the item "Born This Way (Bonus Track Version)". In five to seven business days, a credit of $5.16 should be posted to the credit card that appears on the receipt for that purchase.
I hope this information proves helpful in resolving the problem. If you have further questions, please reply to this email and I'll be happy to assist you. Have An Awesome Day!
Sincerely,
***
iTunes Store Customer Support

Specific request: I have another music purchase question (explain below)
Item title: Lady Gaga's Born This Way
Details:
According to the countdown to Lady Gaga's "Born this Way" album there was not going to be a pre order of "Born this Way" on iTunes.
Instead, one would buy the singles of the album and then when the album came out, one would do "Complete my Album" and get the rest of the songs of the album at a discounted price.
The "Born this Way" album already came out and it is not listed on my Complete my Album page. Instead of the discounted price, it shows me the regular price on both the normal and bonus track versions of the album.
Here's a list of the singles from the "Born this Way" album I purchased:
$1.29 Born this way
$1.29 Judas
$1.29 The edge of glory
$1.29 Hair
The normal price of the "Born This Way (Bonus Track Version)" is $15.99, with the singles I already purchased (witch add to $5.16), iTunes should be displaying a discounted price of $10.83.... and it doesn't.
Would you work your Apple magic and fix this please?
Thanxs! 🙂
