Only a limited number of single seats remain available as Cardiff Blues versus Scarlets heads for a sell out on New Year's Eve (3.15pm).
With less than two weeks until the Guinness PRO14 derby, a small allocation of tickets have been returned by the Scarlets and can be purchased by clicking here.
Terrace tickets are also available, priced at £18 for adults, £14 for students and £8 for under-16s.
The Blues have won their last five first team fixtures at Cardiff Arms Park, stretching back to their 43-29 PRO14 victory over the Dragons in their last Welsh derby.
