Hey guys! Consider yourselves lucky! Here, in Portugal, you get a 4 Ball Can (which is the most common), for about 5Euros wich is round about 6.5USD. You still can get some good deals buying packs, but even that way and buying at tennis clubs, it's not easy. Relatively to brands, they're sold at very similar prices. Most Common here are Head ATP and Champ. and Wilson Champ. In relation to Price/Duty id go for Head ATP. Even in hard courts they hold for a while in terms of felt and pressure.
