Pinto beans are two pounds for a dollar at the dollar store. When you can find them. I have repeatedly going to three different dollar trees and they have had no pinto beans. At a dollar a pound, pinto beans are not a bargain. They are cheaper at Winco in the bulk isle at .69 as of today. I checked. They are also .50 a pound at Costco of you can use a gigantic bag.
Oatmeal is not a bargain at the dollar store. It is cheaper in bulk at Costco. .Rice is a lot cheaper at Costco in bulk sacks.
Feta cheese is 1/2 price at the dollar tree vs Winco.
Winco has cheaper Hunts spaghetti sauce.
Dollar tree has pasta cheaper - Barilla when they have it.
The expensive really good French type cookies are a dollar in stead of four dollars.
Bottom line, you can't say dollar tree is cheaper unless you know your prices. Although. I can pretty much be confident that dollar tree is cheaper than whole foods! LOL.
