62 or 7O percent nitric

My local supplier has 62 tech grade and 70 reagent grade for 34$ and 40$ in 2.5 liters are these good prices and which one should I get?

Either one will work fine,but the price is not great......it all depends on what you have at your disposal.Most places online sell it for upwards of $100 per gallon,or higher,but I can get it from a local place here for less than $5 per gallon with an account.
