Anything higher than 200k imo is overpriced. Easy drops from mostly easy NMs. I'm considering him generous for offering 300k.
I've never seen an advertised price for just about anything in FFXI that didn't spurn some people to say "that's too high!" while others simultaneously say "that's kinda low?".
Currently I see FFXIAH bazaar/wanted prices for Shells @ anywhere from 100k to 1000k, across all servers. So, yeah, 300k is normal/reasonable.
