NEW YORK ( TheStreet) -- The holiday price war is, as they say, on. Retailers across the sector are attempting to lure shoppers with bargain-bin prices and blockbuster promotions.

But cheaper doesn't always mean better, and as retailers roll down prices, some stand to be hurt.

And in our latest weeklong retail poll, TheStreet users (45.8%) say Sears ( SHLD) is the name most likely to suffer as a result.

The department store has been trying to play with the big boys, mirroring some of the steps taken by discounters like Wal-Mart Stores ( WMT) and Amazon ( AMZN).

Last week, for example, Sears announced that it will be offering weekly Black Friday promotions leading up to Christmas. The retailer will offer a blockbuster promotion every Saturday starting this weekend.

The company also announced it will reward shoppers who purchase books from its list of highly-anticipated new releases, with a credit equal to the purchase price -- up to $9.

Macy's ( M) ranked second in the poll of the retailers most likely to suffer from the price war, garnering 39.5% of the vote.

We haven't heard much of the department store's plans for discounts this holiday season, as it has been more focused on introducing exclusive items, like its Threads & Heirs men's line. But without blockbuster deals daily and early in the season, will it be able to compete?

Target ( TGT), meanwhile, placed third with 5.8% of the vote. The discounter announced on Friday that it is expanding its free shipping offer. Now shoppers can get free shipping on 50% more items on the retailers Web site.

It also is lowering prices on books and toys.

Wal-Mart has been leading the way when it comes to heavy promotions for the holidays, and TheStreet users say the company is better able to handle the resulting pricing pressure. Only 5.4% said the discounter would suffer due to price cuts.

The behemoth retailer has already cut prices on toys and highly anticipated new releases.

TheStreet users say Amazon, with only 3.5% of the vote, will be able to best weather heavy discounting. Like Wal-Mart, it also lowered prices on upcoming hardcover books, but this tactic of lowering prices is one the e-retailer has took every holiday.
