Carrefour Hypermarche's 3 for 2 Sale

Right now, Carrefour supermarket is having a fantastic sale, three items for the price of two (what we usually call "buy 2, get 1 free"). Not everything advertised is something I'm interested in, but there were some things that I had bought earlier and which I use regularly.

Plastic freezer bags for leftovers, tomato sauce, lentils with sausage, and shampoo. Also mug cups and bowls (mix and match). And for my daily dose of Vitamin C, 1L cannisters of orange juice (again, 3 packs for the price of 2)!
