So my husband was just offered a $150 CLI on his Credit One card. Current CL is only $300 
I was super excited, because we are really trying to "fix" our utilization, but then I realized they are going to charge $24.99 for the increase......so my question is is it worth it?
Credit one will charge a fee for everything. CLIs, adding AUs, etc. Just use them until you don't need them.

Way too many fees. I looked into it when I was just starting out. Something about paying $100 a year for a few hundred dollar limit didn't sit right. IMO I would look for a better card. Credit Unions are where it's at if you can only get a secured card. Most of them even offer a credit builder loans.
Good Luck!
