If they are bareroots, you need to get them in water soon. If they aren't bareroots, plant them in pots, water them and put them in garage and take them out when the weather is better. You need to plant them when you usually do, or when freeze threat is over. OR, wait until a CR comes to this post, lol.
Those are two beauties you got. You must be an addict braving a snowstorm to buy roses, my kind of person.

Yes, Carla, I'm nuts. This is a most ridiculous question but how do I know if they are bareroots or just dormant? They have nice thick canes so that is at least a good sign.

They must be bareroots, I've never heard of anything else not being in a pot with soil. Take one out and look at it's roots, how do they look?

If they are boxed roses in the square box they are bare root planted in a growing medium. While many suggest removing them from the box and soaking for a few days, I recommend poking holes in the box and soaking the box and all until the box is completely saturated. While in the box, tiny feeder roots have begun to grow. Removing them from the box also removes the feeder roots. The intent of the box is to plant it, box and all, to prevent disturbing the developing roots and eliminate the stress to the plant caused when planting a bare root.
But, experience has shown the dry box will still be identifible two-three years down the road. It often contains the roots and prevents them from growing into the surrounding soil.
Not so if you poke holes in it and completely saturate the box by soaking. The more surface exposed to the soil, the faster the box decomposes. Those I plant that way are completely decomposed by the end of the first season in the ground. Saturating means water the plant should have is not soaked up by the box. Being wet helps it break down faster also. As a bonus, any feeder roots formed already will not be disturbed lessening transplant shock and stress. Usually new top growth will not be affected or need to be removed.
If you plan on keeping the boxed roses for awhile before planting, poke a small hole in the top and water it. The box will become wet and sag some but the growing medium will not dry out. I've seen unsold boxed roses in the original box in mid June, four to five feet tall and blooming. Unlike body bagged roses, boxed roses will root absorbing the nutrients in the growing medium.

Karl, thank you for that excellent advice!
