I did mine in late June, 5 cards
Pen Fed $9.5k
US Bank Cash + 8k at approval, 11.5k (CLI after 2 mos)
Citi Diamond Pref 5k
Then I went to the garden, but came out (technically) because I got a new account when they upgraded my Walmart to a Discover. So I said what the heck, and apped for the NFL Visa Sig, approved for 5k (I could use a free $400). This was the only 'deferred' decision, all the others were instant approvals. I will probably combine this with my unused US Airways MC sometime soon, since they gave me the lowest APR for the NFL card (13.24), and my airport is a Delta hub.
So that's 6 cards, for a total of $51.2k. It has been a good credit year. I keep getting pre approvals for BOA 3-2-1 cards (1 a week for past 3 week. I will not bite, since Barclays warned me of AA if I get new cards in next few months.
