I was in the market for a new washer and dryer. Fry's B&M is advertising up to $500 off LG combos through 9/2. Instore I found the following LG combos to be lower than Best Buy, Home Depot, or local appliance retailers, e.g.:

WM2487HWMA/DLGX7188WM (white) $1949 (MSRP $2470)
WM2455HG/DLG5966G (pearl grey) $1849 (MSRP $2270)
WM2455HW/DLG5966W (white) $1649 (MSRP $2070)
WM2233HW/DLG3744W (white) $1599 (MSRP $1870)
(Above are gas dryers; take $50 off for electric dryers.)

Home Depot has 10% off $399 and up major appliances this weekend, but were still about $200-300 higher than the Fry's sale prices. They pricematched Fry's and then took another 10% off; the extra 10% should not be hard to get because it is a normal scan code after the pricematch, and therefore not part of the manager override.

So I got the WM2487HWMA/DLGX7188WM combo above for $1949 - 10% = $1754. I did pay local sales tax, but there's free delivery after delivery rebate and $200 in utility rebates in my area.

For those shopping for a washer/dryer, Fry's also had other brands of washer/dryer combo's on sale (not carried at Home Depot so no add'l 10%):
Frigidaire ATF8000FS/AGQ8000FS (black) $1299 (vs $1548 on sale at Best Buy)
Samsung WF328AAW/DV328AGW (white) $1549 (vs $1726 at Best Buy)
Samsung WF448AAP/DV448AGP (platinum) $2140 (vs 2491 at Best Buy)

If you really want to push it, Home Depot also promises to price match 10% below a competitor's price, but YMMV. The sales associate who rang me up said that only applies to normally stocked items, while most appliances are considered special order. But it's really up to the manager to approve during the pricematch override; the associate did reveal that on occasion they did pricematch + 10% add'l pricematch + 10% off appliances sales, though usually to friends/family. I was nice to the guy so he probably could've gotten the manager to give me the add'l 10% pricematch if I really begged, but I was happy with the price I got.

FWIW the washer I purhcase was rated #1 by CR, from what I read. It does have the touted new steam functions that are of debatable value; but it is apparently a well-rated washer nonetheless.

I was in the market for an LG SteamWasher WM2688 (the purdy blue one) last Thursday and HD wouldn't accept a Lowe's coupon. The MOD said they had a 10% Labor Day sale going and accused me of trying to "double dip" which would jeopardize his job. I pointed out that I prefer to keep my business with HD, but the Sears down the road would match his sale price, give me another 10% of the difference, and let me use a Sears.com 10% web coupon to boot, so was he sure he was willing to lose a sale? He let me walk, and I took my business to Sears where I got it for $1060 + tax. Even better, HD didn't have delivery slots until late next week, while Sears got it to me less than 2 days later on Saturday.
