I pretty much had thought that they didn't make money on delivery because on average drivers make $5 - $8 per shop/delivery. Free delivery with $x in groceries also confirms that they are making a margin on groceries, which I've heard is as much as 30% but I guess that depends on how often they update their prices and if there are sales going on at the stores they shop at.
