Would love to hear how you're using them! Personally I've used mine for debt consolidation of high interest credit cards, as well as investing in startups.
Business purchases in my contracting work to receive "net20" discounts from my supplier, then pay back when my customer pays me. Wash, rinse and repeat...
@Rebekah Waller Yes, I buy equipment to install from my suppliers, pay their invoices in 20 days for the discount from a policy loan if necessary, then pay the policy loan when my customers pay me.
