I just discovered this gem of resources from a Wesleyan perspective:
https://www.logos.com/product/26963/wesleyan-theological-perspectives

Each volume is a collection of essays - many from well-known Wesleyan scholars. It is on sale this month for $49.99 and with my $50 coupon for being an early adopter of the EEC, it was actually free to me. If you are a fan of Wesleyan theology, this set looks like it is worth adding to your library.
