For a good number of years, Amazon, import CDs, and others were using the extra-long LP mailers. these are the ones that are a few inches wider than the LP record in one dimension and about the size of an LP record in the other dimension. But as of last year sometime it seems that everyone is gone to more traditional LP mailers. These are standard square-shaped mailers. I'm wondering if this was done for cost, or they just decided that the extra wide mailers weren't useful or necessary.
