I'd bring them in if you think you could get them in the ground in a few days when it's a little warmer. If not, dig a hole, bury the whole pot, water and mulch, mulch, mulch. That might buy you some time until spring if they're not root bound. Out of the 6 bushes I've bought the last couple of weeks, 2 were root bound.

Good Luck!

I have a bunch sitting out in pots also.

I'd put them somewhere where they will be protected from frost, but unless they frost or freeze the cold temps will be good for them to get them ready for putting them in the ground for winter in the next couple of weeks.
