Rebel.com does not have a domain backorder feature at this time. We do however have a partnership with Pool.com, a domain backorder company which offers free backorders, deleted domain searches and keyword alerts.
Pool.com offers the following TLD backorders:
All successful domain backorders are priced at $60 USD, which includes a one year registration of the domain. If the domain is backordered by more than one individual the domain will be up for auction for the participating parties. Pool will contact the account holder's email address for information regarding the auction process for their backordered domain.
If you would like to place a domain backorder at Pool please create an account with them here.
