Pretty sure you need to order them through My ProV1.

Last year they were only online.

Just online through Titleist.

My guess is online. Very rarely do you see Titleist logo balls like these unless your local pro shop or local golf store orders some. I've seen MLB logos but nothing like this.

I picked up a box. I love the shamrock and 17. I don't think they're available in stores

Wouldn't make sense for a store to stock them as they would be in low demand on March 18th.

Coincidentally, I ordered a dozen on Tuesday for a couple of best ball tournaments I play with another of Irish descent. They shipped from New Bedford yesterday and will be in WI on Saturday. There were shipping options for shorter deliveries.

Mine should be arriving today. They're great but I wish the logo was actually a shamrock as opposed to a four-leaf clover. I'm kind of a stickler for such things.
