K. Jordan like most creditors that offer closed loop lines of credit will offer credit lines that are rather low to start with upon pre-approval.
Pay it down within or above the agreed terms, and they usually jump the credit lines up significantly.
If you have a thin or no credit history, they probably offer $100.00 min.
It's not unusual if approved for a major closed looped creditor to offer $250.00 for a popular brand such as Comenity for Victoria's Secret, or Synchrony for Belk/JC Penny, etc.
However after making a few purchases, paying the balance off reasonably, and using the credit lines sensibly they will extend further credit lines.
Sometimes you can call in and ask for a larger credit line, and many times they will boost it higher, although that is determined by your credit history.
Remember it's not the amount of credit that matters, but how much you can use by need, not wants.
Some creditors I have found are far too generous in their credit line offering, like really how much does a person really need such as $25k in a single major credit card line? Considering in modern days a person that has such credit lines, have plenty of earnings, thus disposable income, which equates to them have a healthy bank account, in which all now come with a debit card with a major VISA/Mastercard logo.
I think all credit should be modest amounts not to exceed $2,500.00.
I don't believe anyone needs or really uses amounts above that threshold, over a yearly period.
