I was watching television yesterday and thought to myself "why not call and see if there are any SP CLIs I can get".
First I called Barclays JetBlue MC (6 months, always paid on time) and inquired about a SP CLI and it took all of about 3 minutes-- increase from $3,000 to $4,200!
Next I called BP Gas (aka Synchrony) and inquired about a SP CLI (5 months, always paid on time) and in about the same amount of time- increase from $600 to $900!
Not too bad for a Sunday afternoon!!
