So,
@NorCalVol67
Wednesday morning at 7:34 I sent an email to Maxwell House of Books in California thru Abe Books. Found out Amazon is it parent company. Anyway, I asked about the 3 volume set I was interested in. Abe Book guarantees that sellers will respond within 2 business days or you can contact them.
I was afraid the set would be sold so I went ahead and ordered it Wednesday night. By Friday morning I hadn't heard from them concerning my email or received confirmation of my order. So I sent Abe an email. 2 hours later Maxwell sent a confirmation it was shipped. Today I got an update that it was in Ft. Myers and would be delivered tomorrow. Lulz.
