Amazon already has its hands in everything from groceries to tablets, and now the online retail giant might soon become your go-to destination for buying in bulk.

Amazon is planning to launch a new business called Pantry, which will compete with warehouse club stores like Costco and Sam's Club, according to a new report from USA Today, which cited three unnamed people familiar with the effort. Pantry is slated to launch in 2014 with around 2,000 products typically found in the center aisles of grocery stores, like cleaning supplies, pet food, and dry grocery items.

The service will reportedly be targeted at Amazon Prime members. "Amazon will let Prime shoppers put as many of these items into a set sized box, up to a specific weight limit," according to the report. "If the products fit and they don't exceed the maximum weight, Amazon will ship the box for a small fee."

Amazon did not immediately respond to a request for comment.

This isn't Amazon's first grocery endeavor. The company this week expanded its grocery delivery service AmazonFresh to San Francisco after launching in Los Angeles this June.

Amazon has been testing the grocery delivery service in its hometown of Seattle since 2007. Rumor has it that the company is looking to expand the service to 20 other urban areas next year, including some outside of the U.S.

Those with access to the service can fire up the AmazonFresh website or mobile app, order their groceries online, and have them delivered right to their door. Amazon offers a wide selection of fresh produce, pantry, household, health, and beauty goods, including items from local restaurants.
