BiblioBucks are our store credit that can be used when you check out via Biblio.
If you preregistered, then you may have received some Bibliobucks to use during the fair.
The easiest way to use these will be to add the item you want to buy to your cart and proceed to checkout. In checkout you will see the Bibliobucks and will have the option to apply them as payment for your order. Once you apply them by clicking the apply button, then the amount to be charged via credit card or Paypal will be reduced by the amount of Bibliobucks you apply.
Note: if you received your Bibliobucks in a different currency, then be sure to choose that same currency in checkout.
If you choose to contact the dealer to make payment offline, then some dealers may be willing to honor your BiblioBucks credit, and Biblio will reimburse them. If they do not you can simply checkout directly on the site.
The BiblioBucks awarded for Biblio.live must be used on items in the fair and will be removed after the end of the event.
