Then you may not get a month sub. I've been burned by that before. Same situation: game went F2P and boxes were cheap. Got the thing home and the code was no longer valid.
I have no idea about SWTOR. You might want to ask on the forums before buying.
Don't worry, I won't. Like I said, I was only toying with the idea. Even then I'll probably wait until most of my characters are levelled up to the point where the UI restriction becomes chronic.
I did however have a look at the official FAQ & ToS and it does still say that the first month's sub is included in the price of the game. Still, I have yet to see it spelled out anywhere that a code from a bought physical copy will be honored as such, or if they're requiring people to buy the digital download version off Origin. If it's the latter, I'd just as soon not bother. Bad enough I need that PoS to run ME3, I don't want to support it any more than I already am.
