Welcome to GoPostalMusic, where I have more than 38,000 reviews, almost 99% of it is music CDs, records, etc.   I have been selling on ebay since 1995.  Everything currently up for sale is from one estate and the owner was a compulsive collector of some amazing albums across pop, jazz, classical, easy listening, soul, soundtracks and country.  This is a dream collection;  99% of the records are somewhere between forty and sixty years old and there is barely so much as a speck of dust on the record or a dog-eared album cover.  This is like new/mint.  Purchase what you will from this collection of about 300 vinyl records, everything is in good shape and GUARANTEED.  
The surviving partner of the lot indicated that they wanted their records to go to people who would value them, not just to collect dust rotting on a thrift store shelf.  I will do the best I can to make sure these mint condition vinyl records find good homes.  
Shipping is 2-5 media mail.  Packed and wrapped securely $4.50 for individually shipped single records.  Add $1.50 for each additional record to be shipped in one order.  

Please contact me if you have any questions. And thanks for keeping vinyl alive!
