As lovely as it is, we seem to be feeding the whole local population of Goldfinches on these... we have a tree full of them all day long. We don't want to stop but it is getting rather expensive - they ignore the specially grown teasels and niger seed.
Would anyone mind please sharing their most cost effective online source for buying sunflower hearts? We do already buy in large sacks but wondering if we are missing a better priced source. Thanks.
