Mike,
I just called them and got more info. The reagent grade is 70% and the tech grade is 62%. The reason the tech grade is more expensive is that it comes from "high dollar" Fisher, whereas the reagent grade supply is local.
Here's the great part. They sell 5 gallons (70% reagent grade, I think, but it really makes no difference) in stainless containers for $40 (that's $8/gallon!!!). The rub is that the deposit on the stainless container is $275. When you return the container, you either get the $275 back or get more nitric ($40) in another container. They do the same with 15 gal containers. In that case, the deposit is $400 and the acid is $103 ($6.87/gallon). They prefer you to not rinse out the stainless containers before returning them. They also have sulfuric, 5 gal for $71, no container charge. They also carry SMB and about any other chemical you would need (more than is listed on their website). And, they have lab supplies - beakers, filter paper, etc. Great company with good prices.
If you buy the 5 gal, or larger, containers, you'll need a plastic drum pump (I would get 2). You could pour the acid out but I feel the pumps are safer. The pumps are usually $10-$20. Using them can be dangerous, though, if you use them wrong. I can tell you how to use them safely if you want. There are 2 basic types. Here's good photos of the one I prefer. It's more heavy duty than the other one and it will last longer. Note the large red section is octagonal, whereas the cheaper one (usually green) is round in that area. That's how you can tell them apart. I imagine Industrial carries both. The cheaper round type works OK but it's more flimsy. I would get a dedicated pump for each type acid. That way, no cross-contamination. Also, rinse out the pump with water immediately after using it and hang it up to drip dry. If you leave acid in it, it will ruin the valves.

If you do buy 5 gal or more, I would also buy some 1 gal plastic chemical jugs from Industrial to transfer the nitric to. They're cheap. I think they come 4 in a box. You'll also need 3 or 4 new buckets.
