Check Consumer Reports - remember that the model numbers can vary based on the store at which the appliances are sold (so Sears might have a different number than Home Depot even on the "same" refrigerator). Be sure you want a side-by-side - if you've already had one and love it, that's fine, but a lot of people find that they can't put as much stuff (such as a big platter) in the side-by-sides. Also, if you get an ice maker or a water/ice dispenser, those items take up additional room inside, decreasing your storage space. That doesn't not to get them if you feel they are important to you, but be aware of the space needs.
You can sometimes get floor samples at a good discount. And if something has a scratch in the side that will be covered by your counters, why not? Some stores have discount sections (even another store location) just for floor samples and close outs. Sometimes things go on sale on "Black Friday" but it varies by store. Take the time now to research a couple of preferred models, then look at the circulars over the next few months if you feel you can wait. Personally, I refuse to shop on that day because it's such a madhouse, but people who love to shop sometimes find good bargains especially very very early in the day. Some states have tax-free weekends - my state has it in August every year. For a big-ticket item like a fridge, that can amount to a lot of savings.
Good luck.
