FAQs

What is Terrace Finance?

Terrace Finance is the payment method for Finance My Cart. Terrace Finance provides an application portal to a network of payment solution providers curated to service a wide range of credit profiles and products. The types of payment solutions available include loans and lease to own/rent to own solutions. Apply through any apply link on our site and the Terrace Finance platform will work to match you with a compatible payment solution provider and return an offer to you. Our agents will then initiate a contract based on the items in your cart and facilitate the finalization with the payment solution provider as well as the supplier for your items.

Why should I consider lease-to-own?

Get what you need now without a credit card. Leasing to own out-of-pocket expenses gives you another way to pay for the services you want or need without delay.  Plus, it gives you the opportunity to spread payments out over time so the payments can work within your budget. This allows you to keep existing savings, credit card, or emergency funds as a buffer for unexpected expenses or other day-to-day needs.

Do I have to have good credit to shop at Finance My Cart?

No! Since we use Terrace Finance as our payment method, customers of all credit profiles have access to programs they may qualify for. While it is easy to find ways to pay when you have good credit, we pride ourselves on having options for folks who fall just outside the top tier as well as those who have low or no credit. Let’s just call it “less than perfect credit”, shall we?

Can I pay off early to save money?

Yes! While early payoff and same as cash periods vary by provider in the Terrace Finance network, they do each have options to allow you to affordably purchase your item before the agreement term is complete. You will be presented with the available options for consideration before signing.
