Query: Aborted the purchase--not as described.

I accepted an offer of the Pentagon Papers, a four volume set written by the Defense Dept. and published in 1971. The offer stated "four volumes". I had earlier purchased the above title from Amazon only to receive one volume, so I contacted the seller to insure this offer was for FOUR volumes. Seller said "oops-it is only one volume",. so I canceled the order. It appears that sellers do not really look at the wording of their offers, and Amazon does not check them. Oder at your peril.
