Actually, if you're not in need of large quantities of either, your best bet is ebay.
Right now there is a bottle of each (30g, about an ounce) for 5.50 USD. Now, I don't know the seller's shipping policies or charges, but an ounce of each for likely less than 30$ isn't a bad deal for chemicals you'd likely have to special order from a supply house (either in bulk, or 500g ACS reagent grade stuff, not necessary unless you're doing analytical work with it; that's assuming they sell to individuals as well as organizations (not usually)).
Ebay can be a pretty great place to pick up nice stuff: my crown jewel of ebay purchases was 13 oz of pure sodium metal for about 50$, around 5 years ago. Still got most of it
