That online bulk store is really high in volume but a great price for the items that we would get. I have done intense volume of bulk in the past and I have a friend who filled an entire train car with food and building items before Y2K (and has been using them since) so I know how to store the foods... but buying in bulk for me means 10 lbs... not 30. you know? Something that I can see the end of using so that I don't get sick of it and let it spoil. So I don't buy in those intense quanties anymore.
The biggest one we have around is Costco. We get lots of our stuff from there because ours carries tons of organic and health foods now. O milk, O eggs, O butter ($9 for 3 lbs, that is what I paid in the grocer for Dairy Gold butter), O berry mixes (which I don't buy because I pick them each year), O cereal (BareNaked), and whole grain cereals (Paul Newman), O Fig Newmans ($5 for three packages), even O lettuces in the back. The other place we have around here is the Co-op. I love our Co-op, but it is a bit pricey for the things I like to get so when we are tight with our budget I shop at our local Fred Meyers. They have wonderful bulk selections. But it seems you wouldn't be asking this if you had something that avalible to you.
I would check out
Asure Standard You may have to get together with friends to split up some of the items because they come in HUGE quanties sometimes... but it is a great way to get what you want delivered to a site near you. Start small and split every thing with friends in 1 lb sets. Then you will not spend too much and you will also be able to try more things. Then once you know what you love from there, you can put in your own orders (smallest has to be $300 if I remember right) and stock up on what you love to have on hand once per year or whatever you need.
Good luck!

ETA: Sometimes you can get one jar of things for a great price to try before you go ahead and get the "bulk" like this:
Organic Wild Blueberry Spread - $2.50,
Organic Baby Swiss Cheese - $4.95, and
Organic Chili Bean Mix -$4.90. Great way to test stuff out when your friends don't want to... lol!
