bulkfoods.com has yellow split peas at a little over $2 per pound for five pounds, plus shipping. They're in Chicago, so shipping to Indiana may be reasonable. If you order $75 or more from them, shipping is just $5. I get citric acid powder from them (I use it in the dishwasher, among other things) and it isn't hard for me to hit $75.
Unfortunately, they don't carry medium rye flour, which is what I'm currently shopping for. Many of the recipes in The Rye Baker call for medium rye flour, and it looks like if I do all 78 recipe just once I'll need somewhere between 50 and 150 pounds of it. I haven't checked the local Sysco office yet, so I don't know if they stock it, but I can get it online for about $1.35 a pound (in a 50 pound bag), including shipping. Not surprisingly, the shipping is more expensive than the flour. If I can wait until summer, I may be able to get my son to pick up a big bag from Stover Company near Pittsburgh for under $21, if they decide to drive out here for their usual summer visit.
Honeyville has yellow split peas, 25 pounds for 40.99, and they now offer $6.99 flat rate shipping. That would bring the cost for 50 pounds of medium rye flour for me down to about $1.24 a pound. Sara Wirth used to order from them a lot, I don't know if she still does, both of you are in their truck route area.
