If you missed out on this and didn't spring for eBay prices, you're in luck. SSD has the Ray Parker Jr. Ghostbusters 10" Glow In The Dark Record Store Day release up for preorder at their website. Priced at 16.99$. It says Back-Ordered for now, but that will change shortly and you should be able to order it as long as they're in stock.
I know the title may be confusing, I'm not sure if this is a repress, a reissue, or if they held some back on RSD for a later release.
