Heard all three of those. Lewis is great and I have Foxygen on cassette as I mentioned in another thread. I mostly just buy new vinyl/cassette releases from the current year (or the past year that I might have overlooked) as that alone takes up enough time/money.
Amoeba has the 15% code every month, usually around the 20th. I found a flyer for the Hollywood store with a promo code...I forget what it is exactly, but it's ten percent off and I use it all the time when the 15% sale isn't occuring. It's either "rack1" or "rack2" or "rack3"...pretty sure it's "rack2" and it always works. Amoeba's prices are pretty damn hard to beat in general, even moreso with the coupon codes.
