It seems like they're doing Starbucks and Sprint stores.

yep. still unclear on the timing though, i've raided one of the sprint stores here and nothing but crickets.

novatierrie: Meanwhile I raided the starbucks on Sunday...? I think

And not everyone who was in that raid got an invitation.

yeah and someone here who raided the sprint store the other day for mewtwo got another raid pass lol

One person in the chat group I'm in who has apparently spent a lot of Real money was talking about rage quitting the game because he hasn't gotten one yet.
