I agree that buying generic can be cheaper-sometimes. If I need something in a pinch and I don't have a stockpile of it or coupons to combine with a sale-yes, I buy generic.
But, the way I try to do it nowadays is buy multiple papers, print internet coupons-trade coupons-whatever I can to get the most coupons of things I know I need/buy. I combine those with BOGO sales, clearance, and stack store coupons with manufacturer coupons. Most of these things I buy on sale are not generic, but I get them for pennies or for free. Seems to be working out for me so far.
As far as the dollar store, I do still go for holiday stuff (decorations) and little knick knacks, but don't shop for toiletries or food there anymore. I usually find it cheaper in other stores---especially Walmart.
It is great to save money on your everyday necessities. It leaves more money for other things-especially if you need it to
pay off debt. That is how I started couponing in the first place.
