Reverb Bucks are credits towards Reverb purchases. They are available for use on any listing where Direct Checkout is a payment option. Please note that Reverb Bucks can not be used towards purchases via PayPal, only towards credit card purchases through Direct Checkout.
Pro-tip: Get your Direct Checkout earnings dispersed to you in the form of Reverb Bucks, and you'll receive a 1% discount on items you buy using those Reverb Bucks.
No worries, if you decide later you'd rather have cash, you can withdraw your Reverb Bucks using the "Request Money" button here.
Once your Reverb Bucks are in your account, you'll see their amount subtracted from the item price during checkout.
