TCM Kino Classics sale
 

Not sure what shipping is like at TCM, or if it's free, but they've got some ok pricing on about 50 Kino KL Studio Classics discs at $6.55/$6.95, plus additional titles at $8.25/$9.95/$10.95, although those latter prices would be better suited to Blu-rays.

The cheaper discs are also part of TCM's 'Big Red Bag' sale:
