Nice haul Jake. Did you find those in the Tri Cities?
Unfortunately no. There is only one decent place to get new/used vinyl in TC, Adventures Underground, primarily a used book store. The other place has absolute dreck. Occasionally I'll get lucky at the thrift stores or an estate sale.
I went to Yakima on Saturday 4/17 for Record Store Day because there was one place that was listed on the Record Store Day website, Off The Record, with a link to their website which stated they were having a big sale that day. Half price on all used vinyl plus a few deals on new vinyl. Good haul there having spent ~$225.
My buddy John Hoffman ran across an ad on Craigslist for a shop in Union Gap called That 70's Shop and they touted vinyl as well as vintage equipment plus memorbilia and antiques. Checked it out and they had a lot of vinyl so I ended up dropping another "C" note there. All jazz titles including all the ECM records in the list plus a few other jewels. Owner is a nice guy but not part of the Record Store Day group. John said there is another place that is in a coin dealer's shop but I didn't make it there this time around, maybe next time.
Next year I'll try to make it to PDX as there are some great shops there plus a new acquaintence who resides there told me about a guy in Tigard that has a warehouse full of classical. Sells by appointment only.
