Independent record stores are also a great way to buy new releases, as they often give higher cuts to smaller artists than bigger stores do, especially if you're buying music from someone local who can drop off records on consignment.

Discogs is a mix between a personal catalog of your own record collection and a marketplace to purchase hard-to-find records from others. Prices can often be high for super-rare vinyl, but this is a good place to browse to get an idea of the relative prices of releases you're looking for.

Prices range from $25 to hundreds, depending on what you're buying.

EIL looks like it hasn't been updated since the early 2000s, but the rare vinyl marketplace is still the only place you'll find some exclusive releases. With 250,000 different records in stock, the UK-based outlet is a great place to find rare European music that may never have made it stateside. “Yes, we know the design of our website looks a little bit dated to some, but others think its cool retro looks match the records we sell, and we focus our time on buying and selling mint condition reco...
