The grocery industry is in the midst of a big shakeup.

New discounters like Lidl are entering the market to challenge incumbents like Kroger and Walmart, as well as other established cut-rate grocers like Aldi.

And coming completely out of left field, even Amazon is getting in on the action with its plan to buy Whole Foods Market.

Though it’s still early days for the intensifying competition, here’s a look at who’s winning the battle on price right now…

The battle for your grocery dollar heats up

The supermarket segment has seen an influx of non-traditional players. Here’s a quick rundown of what alternatives might be near you:

• Dollar stores ‘ For example, Dollar Tree has a refrigerator/freezer section in larger stores and everything is $1.
• Hard discounters ‘ Aldi and Lidl have small format stores stocked mostly with house brands, and they will save you up to 40% off your grocery bill.
• Warehouse clubs ‘ One warning: A deal is not a deal if something is too big and goes stale before its time.
• Salvage stores ‘ They sell food that’s in dented cans, past expiration date or otherwise unsellable in a traditional supermarket. Though the savings can be tremendous, this is not for the faint of heart! Find salvage stores near you.

With all the variety of new players out there, one strategy to save money on groceries is to simply change where you shop.

If going to any of a number of different stores could be an option for you, it pays to know who has the best price each week!
