Well... filed a Paypal dispute against Air Vinyls. They're really leaning into this "no refunds" bullshit, even though it's explicitly always posted right after explaining that the mockups might not be exact and doesn't say "no cancellations" anywhere. So... that's that. Fuck them.
On a more positive note, I tried to cancel my black copy of Loaded from SIC, citing in part how sloppy the drop was with an extra $15 was shaved off the initial splatter price after the fact, etc. and it doesn't instill a ton of confidence. I got a super quick reply -- unlike with Air Vinyls, who still hasn't responded -- and he offered to upgrade me to the splatter free of charge. That works. So... now I say positive things about them. My tune is changed for now.
Ive found some of the SIC stuff a little sketchy lately but every time I have had a question he has always been quick to reply and fix the problem.
