I was wondering the same thing. Something I saw yesterday online made me think it was online only purchases. I'm going to the DS tomorrow, and I'll ask for sure. I'll report back if you don't get an answer by then.
Lodgelady,
I called the DS this afternoon, ( I didn't get to go, sick children) the online specials are strictly for online, the extra days would not be available from the store. So I guess I'll be ordering them.
