TennisBargains Tip:I personally recommend getting this: Case of 24 Cans of Gamma Pro Tour Balls
You can get these Gamma Pro Tour Balls at $69.99 from Amazon with free shipping.
These are one of the longest lasting and overall best performing tennis balls out in the market and a bit hard to find for less than $3/can shipped.
