When they've had the "buy two boxes of diapers, get a gift card" thing before, I bought four boxes in one transaction and gotten 2 gift cards, so I assume it would be the same for you.
A few times a year, they run a 'Buy 3 bags of Starbucks coffee and get a $5 gc' promotion. This is the coffee we use (and a lot of it) and Target has the best price for it, so when they run this sale, I take my coupons (which I almost always have) and stock up. I got 9 bags one time and got 3 gc's...so I'm assuming the same would hold true for the WW deal. Just check the fine print on the tag on the shelf where the product is. If there is a limit, I would imagine it would specify that there - if it's not in the circular.
