Good subject Michelle. I have discovered that not all store brands are bad. You need to get to know what you can trust and what you can't.
i.e. Coffee is insanely priced and we try to stock up when it's on sale. Sometimes we just can't though so I started looking at store brands. I shop at Acme a lot. We had tried ValuTime coffee, which was horrible. We threw it out. Then we tried Food Club which is really a good hearty coffee, comparable to Folgers or Maxwell House, and only $7.99/cn. instead of $9.99/cn.
This week, Acme was running a one day sale on Folgers, my favorite, $4.77/cn. limit 3. We got 3 cans and that should hold us until it's on sale the next time.
I also shop the sale items as much as I can, buying only meats etc. that are on sale.
