I'm a big fan of store brands. I practically live off President's Choice (Loblaws) and Merit Selection (Loeb), not to mention the Trader Joe's stuff now that I'm in the States.
But once in a while, I come across a really crappy product, one that screams "inferior." Some recent cases:
-America's Choice (A&P) instant pudding: tastes like chemicals and chalk
-Pathmark yogurt and veggie baked beans: both were bland and runny
-ShopRite cereal (the Cheerios knockoff): has the texture of packing foam
Any store brand products you stay away from?
