Over here in Australia, the big supermarkets are just starting to ramp up their "Own Brand" strategy to include everything. They used to have cheap, generic products, and are now branding everything with either "Woolworths Selects" or "You'll Love Coles".
I shop at Coles because I used to work there, and the "You'll Love Coles" are at times better then store brand, and certainly when you look at price.
I buy Barilla pasta because my boyfriend prefers it (And I've noticed that when it's Al Dente, it actually feels Al Dente... It's still strong, whereas some of the others are coming apart or are too tough still), but it's the same price as most of the others. Imported Italian canned tomatoes are also almost as cheap as home brand, and have less bitterness... I suspect the seeds are removed before crushing with the La Gina tomatoes.
I also splash out for Olive Oil (I like something with a fragrance and flavour), Soy Sauce (the cheaper varieties are too high on salty and low on flavour) and Balsamic Vinegar, but everything else I'll take as cheap as I can... Being a student hurts the pocketbook, but I'm trying to keep it from hurting the palate.
