So here's the deal. I have a 723 TransUnion, 734 Equifax on Vantage and 740 Experian FICO scores. I must say this scores will probably go up in a few days cause i made a big payment and I have 100% on time payments, when my score changes, it usually goes up or down 2-3 points the 2nd of the month and then shows the full change on the 6th or 7th day. I just got from 721 to 723 TransUnion today.

I've been working on my credit for 1 year (my first time), so is pretty young. I have 2 Capital One credit cards, Quicksilver with a 1500$ CL and Platinum Secured with 500$ CL, also a store credit card which I can only use on that store with 600$ CL, 2600$ CL total on my general credit.

I usually go to Costco every week, but as you guys might know, Costco does not take any other Credit cards that are not Visa.

I'm pre qualified for Amazon Prime Visa card, with a very good odds of approval on CK. Also credit karma and Experian shows me the Costco Anywhere Visa with good odds for approval (which i've seen it's pretty freakin' hard to get approved, requiring a 800 score according to google), also have the Chase FU credit card in mind but i have fair odds on CK for this one.

So, should i go for the Amazon Prime Visa, try my odds for the Costco Anywhere or wait a couple months to improve my score and credit age? Last time i got a new credit card was 8 months ago.
