Always some great zero interest balance transfer options at bank rate.com. So me can get you 15-21 months of zero interest. There is usually a small fee to transfer a balance but the benefits typically outweigh the fee.
You can also consolidate at a bank or credit union with a debt consolidation loan. This will aggregate balances into a single loan at usually a lower interest rate than a credit card. If you can spread it out over 5-10 years you will also dramatically lower your payment instantly.
In both these solutions you’d be wise to continue to pay your original non consolidated payment if possible to quickly pay down principal and eliminate the debt.
