AliExpress (and its many third-party sellers) takes up to 50% off sitewide during its Singles Day Sale. Many items bag free shipping; otherwise, it starts around $2. Deal ends November 12 at 8 am ET. A couple best bets:
Baby Diaper Bag with USB for $27.87 (low by $5)
17-Piece Polymer Clay Ornament Set for $3.21 (pictured, low by $4)
Note: Many items ship from outside the US, and may take up to three weeks to arrive.
These retailers offer some of the most consumer-friendly price-match policies anywhere.
