Looks awesome! As a side note, 'vinyl' is both singular and plural. I'm not sure if English is your second language, but I wouldn't worry about it. It's even tricky for people that speak English as their first language. So yeah, don't say 'vinyls.' Vendors might try to rip you off because it indicates a lack of familiarity with vinyl. If using 'vinyl' sounds weird/awkward in a sentence, substitute 'records' for it. (I really hope this doesn't come across as condescending/pompous. I just wanted to point it out and help you guys out.)
Oh didn't know. I don't really know much about it honestly, I was just keeping company to my boyfriend :) But the funny thing is that somehow the random LPs I spot are usually the more valuable ones. Without knowing the artist of anything about vinyl. My boyfriend jokes that I have an expensive taste just wired into me. During this trip, I scored a Japanese print of a Jefferson airplane album for 1$ that is worth around 20-30$.
