Each ball is marked a number: 1, 2, 3 or 4. what does this number mean? tia.

Typically, in any can of balls, you will see the manufacturers name (Penn in this case) and a number. If there are 3 balls in a can, all will have the same number. The reason for that is that if you remember your ball's numbre and the manufacturer, you can easily find it if the ball gets away into another court. That is really the only reason a ball is numbered. The number does not designate what type of a tennis ball it is. I hope that helps! Take care. David B.

If the tennis balls were transported by flight, will the air-pressure damage the balls (resulting in dead balls) ?

If the shape of the can does not change, the pressure inside the sealed can will remain consistent. The pressure on the outside of the can will not affect the inside. Temperature, however can affect the pressure. Higher temp, more pressure. Not sure how that will affect the balls.

Does it really take 2-5 weeks for delivery?

Should take less than one week-- 10 days at most.

Just confirming that these are 12 cans of balls (36balls in total)

COSTCO Warehouse sells 20 cans for $35.99 everyday prices for the exact same types of lower quality balls, can you provide a reason why anyone should buy here? THX
