Combining Best Buy Mastercard with Diamond Pref?

[bearclaw84]

Is it possible to get Citi to combine my limit from the Best Buy card with my Diamond Preffered card and then close out the Best Buy card? I really ahve no use for the Best Buy card anymore and would much rather have the available credit on my DP card as I tend to use it more often. I don't know how they treat co-branded cards and if they would even consider something like this? Thanks for any help you might have!!

It's not possible because the My Best Buy MasterCard is issued by Citi Retail Services and your Citi Diamond Preferred is issued by Citicards US.
