Liking a bargain and liking to bargain are two different things, but now Amazon claims it can satisfy both needs, thanks to a new feature rolling out Tuesday that lets you "make an offer" on certain products.

The feature is only available for certain items such as sports memorabilia, entertainment collectibles and its coin and fine art section. But those interested in buying those items can submit their bids to sellers to get what they want -- a part of the online commerce world normally associated with eBay. All in all, the company said in a release, around 150,000 items on the site have the flexible pricing options -- a number that should expand in 2015, Amazon said.

The program isn't designed to send prices sky-high, as with eBay and other auction site listings, however. In a press release, Amazon says that the "Make an Offer" option give consumers a new option to "buy items at even lower prices." Sellers will indicate that they're willing to sell their item for less than a listed price, giving consumers the option to argue the price down, rather than try to outbid each other. Buyers and sellers negotiate over e-mail, where they can propose, accept, reject or counter each others' offers.

(Personally, I think Amazon has missed out on a great chance to add a "Haggle" button. But maybe that's just me.)

The feature adds another feather in Amazon's e-commerce cap, as it competes with a lot of places around the retail world. Yet Amazon is facing even more competition on that "low-price" thing than ever before. According to a survey from ShopSavvy -- a comparison shopping app for iOS and Android -- found that Wal-Mart has cheaper prices on "over 50% more products" than Amazon and Best Buy. And with Wal-Mart announcing that its online price match policy will now include prices from Amazon, even more of that edge may be disappearing.

Still, the bargaining program isn't for all products. There's no indication that this option will spread to the rest of the marketplace either, so you probably won't be bargaining with anyone for the price of everyday items such as books, smartphones or kitty litter.
