Iceland Summer is working together with Avis and Budget car rentals. We provide our customers the best prices out there! Book your car with us and you will get 5% discount of your rental car. We will provide you with a discount code which you then use on budget.com. If you have already booked an apartment you have received your BCD (Budget Customer Discount code) in an e-mail regarding your apartment booking. If you have lost it, do not panic, you can get the code here.
