I've found that the walmarts with a garden center have the very best prices on the good stuff. For instance, this one comes in at just under $6.00
For the smaller birds... finches, thrushes, etc I just buy a box or bag of this from their pet department. And, there is no milo to be found. Its for canaries and such but what really is the difference anyways. This is under $2.00 for the box or under $4.00 for the bag... a much better deal than the stuff in the wild bird food section.
