I think we mentioned this before, but it bears repeating. The labeling of the product has to agree with the product consistency from one vender to another. If a Walmart product has the same oil bottle label as that sold elsewhere, it is the same product. What you need to watch out for, is for example, a product abeled L42 from one store and L42D from Walmart…then, there is a difference. Otherwise, maybe someone is breaking some deceptive labeling law or whatever by selling retail, different products under the same label. It’s cheaper often because of the negotiated price on bulk. Correct me if you will but, You won’t see lower prices on Apple or Bose products; they don’t negotiate or make special models for Walmart.
