I wouldn't pay anything for a mass gainer. They are all overpriced in my opinion. If you need more calories, just eat more. If that is an issue, make your own gainer. Use a scoop or two of protein powder, some oatmeal, sweet potatoes, veggies, fruits, nuts, nut butters, oils, etc. and blend them together. It is cheaper and you can control the amount of fats, carbs, and protein.
