Supplement Hunt offers the Slim-Fast Protein Smoothie Powder Single-Serving Pouch 100-Pack for $99.99. In cart, the price drops to $29.99. (You may need to apply coupon code "slimfast100" to get this deal.) With $5.99 for shipping, that's tied with last month's mention and $38 under the lowest price we could find for a similar number of servings elsewhere. Each serving provides 12 grams of protein (or 20 grams when made with 8 oz. of milk).
The dollar store is the most amazing place to find bargains for certain purchases. Yes, even pregnancy tests.
