Go to top left of that sites page and shop on the link that says A-Z for your spices ...its where kksuns who recommended that site to me and i shop for a lot of things for our birds and ourselves...in fact i just ordered $40 of stuff for several months of spices for my kitchen and Cappys ...giggle...ya get free shipping when you do that and it last...now for Cappy i get stuff like ...golden flax...parsley...green pepper flakes...celery flakes...fennel...anise ..jalepeno peppers...beet powder when i cant get the beet leaves which he loves...and carrot powder because he doesnt like carrots.... just to name some lol...yah yah he is spoiled...now for the deluxe canary seed mix and the basic budgie go here....http://pet-supplies.shop.ebay.com/Food-Treats-/116494/i.html
half way down the page you will see first the deluxe canary seed mix 2 pounds and then right under it the basic budgie seed mix 2 pounds with FREE SHIPPING...we both also get our seed from them too kksuns and myself ..
You can find regular barley as mentioned and oat/groats on some other sites if you want ill find them for you too later...doing some cooking at the moment ...he eats better than me but ive got to go eat myself now
P.S. as you can see if you read ingredients in most of our seeds we feed ...fortified or not ...there is plenty of millet in it already...and millet sprays sorry to say are most often rather than not ..not fresh...dusty...pieces get stuck in nares etc...plenty of treats to use instead of millet...favorite veggie or something else. Also, as kksums so often points out ..fortifide seeds only have the so called benefits on the hulls of the seeds which our birds DONT eat and the food coloring is horrible for them.
