2-Pack 36-Count Penn Championship Extra Duty Felt Tennis Balls $47.95 + Free Shipping. Thumb Score: +14 Just like the title says. It's been a while since I have seen a $2/can on any balls, and my local Costco sells a 20-pack for $46 ($2.30 per can) on a normal day Now, I realize that balls a personal preference, and I personally quite like these balls - they are firm and quite fast, compared to many other balls. Though I do play with Wilson US Open/Roland Garros on clay quite a bit. I do not find issues with durability on these, and they easily last 3 sets for me (clay or hard surface).
