I am sensitive to the fact that some people on this site look down their noses at eBay, but I have purchased more than 1000 CDs from eBay over the past 10 years and have experienced only one problem; and even then my money was refunded. Moreover, many of the sellers are wholesalers and frankly have no idea of the real value of some the recordings they are offering meaning that occasional ridiculous bargains do surface as in 50%+ lower than the identical used item on Amazon which is indeed a highly reputable site. Finally, it is not that unusual to find extremely rare O-O-P recordings that are no longer available elsewhere. A caveat: I prefer easy and non-contentious transactions and thus almost always purchase from sellers with 100% perfect feedback based on a minimum of 100 successful transactions; I always pay with PayPal or a credit card which insures that ready recourse is available should a problem arise; and I do maintain a list of favored reliable and honest sellers with whom I have done much business in the past.
