How do I delete two old Apple ID's and just use my current Apple ID?

Question

I had an Apple ID with an AOL email, I switched over to yahoo. While making the switch I misspelled the yahoo email address. I could not delete it, so I made another yahoo email address ID. Eventually I lost access to my previous purchases that were associated with the faulty email address even though I was using my current (correct email) to log onto iTunes. I found this out when my Macbook crashed (iPhoto) and I could not access my previous purchases. Eventually I was able to convince Apple Account Security Support that I was the person who set up the account (I am living in Barcelona currently and calling for support cost a lot of euro on a pay as you go sim and holding for 1 hour is a big waste of euro, but I understand that Apple Support is busy BUT, if you (Chris and Tyler) say you will call a customer back if you are disconnected you should follow through, not leave the customer hanging) (A SHOUT OUT TO MERCEDES, SHE FOLLOWED THROUGH!!!) (Chris and Tyler you guys need additional customer training from Mercedes)
Anyway, back on topic. By a stroke of luck, while I was on hold for 30 minutes, I found the crossed out password to my faulty email ID, I was able to view/restore ALL of my previous purchases. So, my problem now is that I still have two unused Apple ID's. I want to delete them and just use the current. I don't want to call Apple again because I cannot waste anymore euro on hold and I do not feel confident that the Account Security representative will call me back, Mercedes is an exception to that. It would be nice to resolve this by email correspondence OR and actual call from Apple Account Security.
On a side note, I have purchased three Apple devices while here in Barcelona. Europe has a mandatory two year warranty, but if you have a US iTunes Account serial numbers written in for warranty information only are recognized by US one year warranty standards. Apple should Should acknowledge this loophole/oversight.
So that's a brief summary as it relates to my question. Sorry for the length of it. I hope I can get some good opinions for a possible resolution for my question/issue.
Thanks

On a side note, I have purchased three Apple devices while here in Barcelona. Europe has a mandatory two year warranty, but if you have a US iTunes Account serial numbers written in for warranty information only are recognized by US one year warranty standards.
Your account isn't US or Spanish or any country but should be associated with the country in which you are resident.  Your US account  becomes a Spanish account if that is where you now live but it is all the same AppleID.  Before you change country make sure you have downloaded and backed up any purchases from your previous country's store.  You will not be able to re-download them again once you change countries and it won't be easy to change countries to the previous one once you lose your payment method for the former country (as well as a wait period).  As long as you have them on your computer you will be okay.
Change the country of your iTunes Store, App Store, iBooks Store, and Mac App Store account - http://support.apple.com/kb/ht6119 - "After you change the country of your account, you won't see the items you purchased from the previous country’s store in the Purchased section."
Even if you do not change country you are not supposed to use your account outside the USA. The iTunes Store in a country is intended for use only by that country's residents, and only while they are in the country. To use the iTunes Store in a country you need a credit card (or other card type if acceptable in a country) issued in that country, billed to an address in that country, and also be physically present in that country when using the store.  You are also restricted to waiting 90 days between country changes.
E.g., "The iTunes Service is available to you only in the United States, its territories, and possessions. You agree not to use or attempt to use the iTunes Service from outside these locations. Apple may use technologies to verify your compliance." - http://www.apple.com/legal/itune/us/terms.html#SERVICE
As for the devices, I believe except for computers the warranties only apply in the country/region of purchase.  If you return to the USA with them you would have to return them to Spain for any service (and no, Apple will not ship them back to another country either direction -- you'll have to get a friend to take them in).
Apple Hardware Warranties - http://www.apple.com/legal/warranty/ - select device, then model, then country, then view warranty button.  Look for:
"IMPORTANT RESTRICTION
Apple may restrict warranty service to the country where Apple or its Authorized Distributors originally sold the Apple Product." - http://www.apple.com/legal/warranty/products/iphone-english.html
