Tractor Supply is the place to buy sunflower seed right now. Their price has dropped from $24.99 to $19.99. per 40 lb bag. I bought two bags yesterday. During warm weather you have to be careful about having too much seed on hand. If it is kept too long small millers will hatch out inside the seeds and eat the hearts out, making the seed useless for the birds. Roger Mayhorn Compton Mt
