Affirm and Gwatney Performance have teamed up to offer easy financing for orders over $500 – without a catch. There are no gimmicks like deferred interest or hidden fees, so the total you see at checkout is always what you’ll actually pay.
Affirm designed its loans to offer you flexibility and control over your budget. Affirm offers rates from as low as 10-30% APR based on your credit. Actual rates will be shown at checkout.
Affirm has a dedicated team in San Francisco at Affirm HQ, ready to answer your questions and help out however they can.
Unlike a credit card, Affirm is not a revolving line of credit. While customers can take out multiple Affirm loans at once, each Affirm loan application is evaluated separately as a closed-end transaction. An application from a returning customer may be denied, however, if that customer has failed to repay other Affirm loans on time or if the customer shows excessive borrowing behavior.
You can pay your Affirm bills online at www.affirm.com/pay. They accept payment by debit card, bank transfer and check.
Yes, when you first create an Affirm account, Affirm perform a ‘soft’ credit check to help verify your identity and determine your eligibility for financing. This ‘soft’ credit check will not affect your credit score.
Affirms tries hard to approve every purchase but sometimes can’t approve the full amount. When this happens, Affirm provides a debit card down payment option so that you may still complete your purchase right away.
Affirm sometimes requires additional information to consider a credit application. Such information may include an active checking account, which helps Affirm verify your identity and your ability to repay the requested loan. If they prompt you for this information but you are unable to provide it, Affirm will be unable to approve your credit application.
