If you're friend is driving on his way up to Virginia, he'll pass by Gainesville, FL just off I-75. There's an LFS (Aquatropics) that has both Nerites and Amanos. I believe they go for $2.99 and $3.99 respectively. If you're interested, call in advance to make sure they have some as they sale out of them pretty quick..., well, the Amanos at least.
