Americans everywhere are preparing for the biggest sale of the year: Black Friday. And with only a week to go, here are some of the best deals to look out for at Costco.

4K televisions are all the rage this year. Costco will have a lot to offer in terms of television sets, but it is important to keep in mind that they will only be discounted for a limited period of time.

For the Vizio brand, Costco is going to have the 70-inch class 4K Ultra HD LED LCD home theater display for only $980 and the 65-inch version of the same specs for $690. Samsung brands are also up for price discounts. The South Korean tech giant's 65-inch class curved 4K SUHD Smart LED LCD TV will be on sale for only $1,580, while its 40-inch class 4K Ultra HD Smart LED LCD TV will be available for $290.

Finally, LG televisions are also up for grabs. The LG 70-inch class 4K Ultra HD LED LCD TV will sell for $1,100 and the 65-inch 4K Ultra HD LD LCD TV will only cost $779.99.

Costco members also have certain special privileges and can check store prices online. Kiplinger spoke to deals experts recently and concluded that out of all the Black Friday deals, there is a specific one to avoid: the unlocked Motorola Moto G 4th-Gen 32 GB smartphone with $55 slashed off the price.

"This deal will likely not meet our predictions for Android phones," says deals expert Benjamin Glaser. "It is eligible for a mail-in rebate store credit, but you should look elsewhere for better straight-up discounts."

Other items to look for are the Xbox One S 500 GB bundle, the Microsoft Surface Pro 4 bundle, the 15.6-inch HP Pavilion 15t 1080p touchscreen laptop, and the Acer 14-inch 1080p IPS Chromebook bundle.
