You don't need to spend ANY money on whey or weight gainers. What you need to do is raise your caloric intake and get most of your protein from food. It's great to supplement with whey if you can afford to, but it's not absolutely necessary.

Tuna at the dollar store is around $.25 a can. And a box of oatmeal is dirt cheap also. Brown rice is super cheap.
