Having competition and choice is good, although I find both brands $$.
Clearly neither is a 'discount' brand, that said almost all brands have an area or two where they differentiate themselves through 'better value'. Either the same product at better prices or a better product at a comparable price.
In the case of FB, look at fresh herbs, for some price savings, not the ones in the clamshell, but the bunches of Parsley and Cilantro; I find FB between 20-50% cheaper on average.
I would also look at Green/Yellow Beans, where the price is more normative, but I find the quality superior, so you get shelf-life.
On meats, they're broadly fully priced, and run promos like others do, but I find, on average, they are more competitive on Pork Tenderloin, consistently pricing it at $11 per Kg at least one week out of every month.
Loblaws tends to run fewer good deals on meat, but bone-in chicken can thighs are often aggressively priced. Also they tend to carry Bertolli Olive Oils at competitive prices most weeks and have some good deals in different sections week to week, particularly on PC brands, and notably cookies. Decadent Chocolate Chunk cookies are regularly at or below $4 per bag (though, you'll typically seem them at $2.79 at NF)
They also like to run an aggressively priced butter promotion about every 8 weeks or so, dropping the price to ~$3.99 a lbs.
