Overstock has a 60-Pack of Mixed-Brand Recycled Golf Balls on sale for only $34.99. Plus, shipping is only $1 through 3/17 (otherwise $2.95) and there's no sales tax (except IN, UT). While these are recycled and of mixed brand, they're well suited for practice or anyone who hits most of them in the water eventually anyway. Plus, you're getting them for just over $0.50 per ball compared to $2-$4 new. Both reviewers said the balls came in great condition.
