Why don't you just call them, explain the problem and ask them to send you some non wrinkled sleeves to replace the defective, wrinked ones ....
Acoustic Sounds Customer Service
I recently made my first purchase from Acoustic Sounds- 3-180 gram LPs and 50 of their poly lined inner sleeves. LPs are fine, but the sleeves were warped when I unpacked. I split into little piles to see if they would relax but never did. They bundle up when you try to put an LP away. So I did receive an RA from A. Sounds, but they refused to pay shipping back. I realize companies have policies but when they clearly have shipped an inferior or defective product, I believe they should look outside their policies and take care of the customer. So now I'm looking for another company (Music Direct?) to buy my analog from and also some inner sleeves that will lay flat. I know there's a recent thread on inner sleeves and I will read for recommendations. Anyone else unhappy with A. Sounds service?
