Vattene- Well it depends. All companies love people with higher incomes. AMEX typically targets the well off, hedge fund owners, bankers, etc, and then there are us regular people who have good credit that they have extended credit to as well. All companies care about income but if your credit is good with no major issues, then the vast majority will approve you (penfed seems to be the exception as they can be PITA as many people here have experienced.) I never wanted any store cards...I've preferred major ones tbh. If used correctly, Credit cards can be like a gift from heaven, if not...your SOL.
Yeah the swipe fees are crazy. At my office (the owner also owns some subways and IHOPS, the fees can be pretty high...I work with the real estate group...but I'm pretty much assigned running around everywhere helping anyone who needs something.) But literally their high. Visa, IME, is usually getting the lion share of the fees since they are the largest branded card company out there (meaning their logo is on the vast majority of the cards) while Master-card is slightly less. The reason why Amex charges quite a bit in merchant fees is because it convinces the merchant that their cardholders are typically more upper-class and well off, thus they will spend more, and therefore Amex will take more swipe fees. Take Costco for example. The reason why Amex is accepted at Costco exclusively is because Costco sells things in bulk and sells them at a slightly higher price then everyone else (but they have the better quality in terms of what you can buy there which is why I myself have a Costco membership-They have quality products for the most part compared to Walmart and Sam's club). So Amex comes in and basically tells Costco to accept our offer because our card-members will spend more here and since they do Costco profits in terms of getting the sale and revenue while the more Costco sells the bigger the fees that Amex will rake in. Same thing with Amazon. Amazon is a Internet Mall that sells everything one can dream of, and the CC's know this and since people buy things in bulk or spend a good sum of money there, they'll make more in fees. Oh and I forgot Discover, Discover is starting to become more accepted as well but they too charge fees that rival Amex, and many do not want to accept it. Example, small merchant is selling clothes. If Visa is charging 3% and Amex is charging 5%, Discover will be around 4%. That's really it....at least that's my theory.
Hopefully it makes sense what I'm saying
