Of the LP's I receive from Amazon, about 20-25% of them come with a serious crease in at least one corner of the outer cardboard jacket, a result (I presume) of the LP being grabbed by a corner of the jacket by the Amazon employee pulling the LP off a shelf in an Amazon warehouse, rather from the middle of the jacket (where the 12" diameter of the LP fills almost the entire height and width of the typically 12-3/8" jacket, thus making creasing of the jacket impossible). I return all LP's received in this condition for a replacement, and about the same 20-25% of the replacements arrive with the same damage. Back they go too, for a third try. Sometimes Amazon does not offer me that option.
I have severely cut back on my buying of LP's from Amazon, it's just not worth the hassle. I made an exception for the upcoming Molly Tuttle album (release date August 15th); Amazon has it priced at $12.99 (retail $24.99)! My sister has an Amazon Prime account, so shipping is free for even a single LP.
