I just couldn't see spending $30+ on feeders at the store. My local grocery store gave me 1 gallon buckets with lids that held potato salad, and I bought 12" diameter plant saucers from Walmart for $1 each. After thoroughly washing all components, I took a utility knife and cut 2"L x 1/2" H openings in the buckets. I cut 4 openings for the feed bucket about an inch from the bottom. I placed in top-up in the saucer so it can be easily filled and the lid can be replaced. They hold approximately 5lbs of feed, which is perfect for my small flock. I cut only 1 opening for the water bucket about 2 inches from the top of the bucket. After filling, I put the lid on, placed the saucer on top, then inverted it to create a vacuum.
