My credit is 606. I have student loans and a car note. I was thinking about getting the Chase Freedom Flex card and use that to pay for groceries and gas.
That's good that you already have an established credit profile. Those student loans are usually deferred during schooling, so how did the score get so low? Did you miss a car payment lately or get something like an unforseen med bill?
Also, i highly recommend not applying for the chase card with a 606 score. Your application itself will lower your score, and this effect is compounded by not getting the credit line that you requested. Chase is known to be stingy with approvals AND hanky with credit limit increases( used for utilization, not for spending)
In contrast to the chase card, the secured card i was talking about earlier was a damn near garunteed bet, that would allow you to set your own "limit" from the jump. The new credit line would also offset the loss from getting your credit dinged. If you dont want to do the secured card path, capital one is known to be liberal with giving out cards to people in the mid to low 600s. I believe they start you with a $300 limit too.
If you do get the card, I agree with your plan to pay for necessities like groceries and gas. Just make sure you keep that revolving 10%-19% balance if you want to upgrade cards (or limits) later on.
Better to go with a Credit Union or bank to get a credit card?
Credit unions by a huge margin. In addition to your credit score, they consider your yearly deposits made into the bank and your length of service with them when approving an application. This would be perfect for op,
@SupaVillain, cause it would only require him to transfer a portion of his 7500 savings into the credit union to get good grace from the onset.
Furthermore, Credit Unions tend to have excellent customer service(only discover card is better) and they tend to be understanding if an emergency pops up cause they often know you by name and can sympathize in a way that traditional banks cannot.
There is 1more perk and 1more bad thing about the Credit Unions, though.
- Perk. They typically offer lower interest rates than the major banks and credit companies(visa, c.One, amex), except for discover card which trends lower.
- Bad thing. Their benefits are trash.
- travel rewards tend to be lacking.
- Your cash back potential is typically limited to 1%, while major banks and credit firms commonly offer 2% or 3% back
- No lounge access when traveling

- Fewer store discounts because they only offer deals for local mom&pop stores, whereas C.One or amex can routinely give you 10% off on major national chains ranging from Starbucks, to Macies, to HP computers, etc
Keep in mind that receiving 10% back on an HP computer purchase, can easily offset the maintenance cost of a non-credit union bank card.
