Other Car Rental Programs/Partners (ie. Alamo, Enterprise, Sixt) - Discounts in Cape Town

Hello,
I will be in CPT for the month of August and am looking for any codes or discounts that would work there. I am not picky about which company I use.
Thanks in advance,
Chris

I have tried priceline and came up with some pretty good rates. For South Africa, priceline offers four companies that they are affiliated with, Budget, Avis, Hertz and Alamo. I found that Alamo had the best rates. Priceline just has an agreement with these companies, but not the normal priceline, bidding for a rental.

I have found that avis.co.za has some pretty good deals (some deals incl. airport tax). The site also offers an auction for car rentals. Check it out.
