It's the same stuff. When the big peanut butter recall happened a few years back - it turned out Peter Pan and Great Value were one and the same. Walmart's not producing food - they're putting their label on it... So keep track of recalls and you'll know what you're buying - and a MUCH cheaper price.
It's the same stuff.
Some stuff may be, but that's not true on it all, or even on a majority. There's another factor in this, too -- and it's that the off-brand stuff is sometimes lower quality raw product (that goes into the finished item), while the "name-brand" (from the same manufacturer) is kept higher quality from cherry-picking the better raw product.
So, the product is made the same way, packed in the same container (different label), but the raw product is the lower quality "rejects" that they did not want in their name-brand.
It comes out the same factory door, it has the same basic container (but different label), it looks about the same -- but it's the lower quality product that they produce. That's what a lot of people don't realize...
BUT -- if you (or someone else) can't tell the difference, then I guess it doesn't matter... :-)
Sometimes. I've not had good luck with the house brand soups that are supposed to be the same as campbells. Meat was very tough, and somewhat sparse. I bought some house-brand wheat crackers one time that were supposed to be the same as Triscuits - they weren't. Not horrible, but not nearly as good and the were all puffed up instead of flat like the real ones.
There's no guarantee that you're getting the same brand either. Yes, you may be getting the same product as Del Monte. Or Heinz (yecch - do you really want to support Teresa Heinz-Kerry?). Or maybe something else. And I bet it changes from one batch to another depending on who has the best deal.
I prefer to buy most items by brand, but I usually shop by price. It is rare that I buy non-perishables at their regular price, even at WalMart. That's not to say that I won't buy some house-branded items. Rice is rice. Flour is flour.
