I bought about 2.5 years ago a LG washer and gas dryer…the models on both were just below the steam as I didn’t see any reason for the steam, it just screams gimmick to me. No problems, they work great. I did a ton of research at the time and they were top rated, but like any appliance, there are always bad reviews for any model, any brand. The worst reviews I read were for Whirlpool, Kenmore. Something to consider is the review on the electronic panels of whatever model you want to buy…. when that panel blows, its pricey to replace, but I don’t remember it being a prevalent problem with LG.
Best Buy will negotiate, Sears was not when I was shopping. I was able to get 1k knocked off between the washer and dryer pair, but keep in mind, they were more expensive when I was buying them 2.5yrs ago than they seem to retail for now, so you may not get as much off each one, but it cannot hurt to ask for a discount.
