Is this really 36 balls or is it 36 cannisters? If its just 36 balls then thats 12 cannisters. You can get 3-pack cans of these for $2 at almost any store the sells tennis balls. The fact they have the original list price at $90 is either a total joke or really reflective of 36 cans, not balls. $90 for 12 cans is over $7 a can which is absurd. $90 for 36 cans is a bit over $2/can which is more realistic. Great deal if this is really 36 cans, otherwise its just standard tennis ball price.
