When buying the Galaxy S24 Ultra, the most recent Galaxy phone Amazon will accept for trade-in is the Galaxy S21 Ultra, which it priced at $135. Samsung values the exact same handset at $600. A mind-bogglingly large gap in valuation between the two companies.

SAVE $350: As of Oct. 9, the Samsung The Frame 55-Inch TV is on sale for $667.99 at Amazon. That's a saving of 41% on list price.

Prime Day deals bring the Samsung Frame TV down to a record-low price. The sale knocks over $650 from the original cost of the 55-inch model.
