ShopPBS takes up to 90% off clearance items during its Summer Clearance Sale. Plus, take an extra 15% off via coupon code "MEM_15". Combined, that's tied with our mention from two weeks ago as the best sale we've seen so far this year from ShopPBS. Shipping starts at $3.75, or get free shipping with orders of $150 or more. Discounted items include DVDs, Blu-ray discs, CDs, T-shirts, collectibles, games, and more.

A best bet is American Experience: Jonestown on DVD (pictured) for $9.99 before the above coupon, $8.49 after. Update: It now falls to $8.29 in-cart and $6.79 after coupon. With $3.75 for shipping, that's the lowest total price we could find by $16.
