Amazon.com has a feature where certain items qualify for a "Buy Four and only pay for Three" promotion. Basically, if you buy four items that qualify Amazon will give you the lowest-priced for free!
This means that, say, if I get these bake racks for $9.99:
and this cute panda bento box for $15.99:
this photo album for $15.58:
and this neat pewter bubble wand to save for someone's Christmas gift for $14.60:
My order review looks like this (using Super Saver shipping option):
Shipping & Handling: $9.71
4-for-3 Promotion: -$9.99
Super Saver Discount: -$9.71
Total Before Tax: $46.17
Estimated Tax: $0.00
Order Total: $46.17
You got free shipping!
Pretty neat, huh? If you play your cards right and try to get items that all cost the same, that's an automatic 25% off. You can find out more about this here.
