I expected this thistle sack to come with seed in it but it didn't and that is OK. I buy thistle in bulk and can fill it inexpensively. The price is good and it is the long bag which needs filling less often. Not being filled is actually a plus since it is a Christmas present and I can take it outside and fill it after my friend opens it.
This is the best thistle sack I have used. The birds flock to it and it doesn't waste as much seed as others.
