35% off everything at Insound (which is closing soon?)
Records, CDs, turntables, speakers, headphones, clothes, books, DVDs and more are still listed for sale. They may not have new releases, but the site appears to still be fully operational. In fact, through some searching we found a 35% off "going out of business" coupon that definitely still works. They've got some nice entry-level audiophile turntables to which this discount is particularly attractive.
The coupon code, which references Insound's parent company Warner Music Group, is WMGFriends35. You apply it in your cart.
