I know this might not be the appropriate place, but I'll give it a shot.

I'm looking for a deal on an adult outdoor basketball. There was a F&F 25% discount @ The Sports Authority I missed out on recently. TIA.

What's the difference between an indoor & outdoor basketball?

Made for concrete versus wood floors - outdoor ones are tougher surface

If you have a Target B&M locally, you might check there. One of ours had a bunch of their outdoor sports stuff (assorted balls, basketball goals, golf stuff, etc) on clearance recently.
