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.

During the Amazon October Prime Day sale, however, the prices on Samsung's latest foldable phones are getting some pretty significant discounts that almost make them affordable. Both the Samsung Galaxy Z Fold 6 and the Galaxy Z Flip 6 are currently discounted for Prime Big Deal Days.

The high-end Samsung Galaxy S24 Ultra, for instance, is currently on sale for an almost-record-low $997 (was $1,299.99), while the iPad 10.2 (2021) – aka the best cheap tablet money can buy – is now available for an absurdly low $199.99 (was $329).

Here are the best unlocked phone deals at Amazon ahead of the official October Prime Day. We'll be refreshing the list throughout the event, so keep checking back if you don't see the phone you want just yet. 65" Hisense U6 Series 4K Mini-LED ULED Smart TV (2024 Model) — $597.99 (List Price $799.99)

Samsung has discounted the majority of its Galaxy S24 lineup as part of Amazon's latest October Prime Day sale. The deals bring the Samsung Galaxy S24 Ultra down to $998, which is 23 percent off the jumbo-sized phone's list price and about $100 off its street price on Amazon in recent months.

It's no surprise, really, as Samsung is one of the brands we usually see major discounts on during big shopping events. July's Prime Day aligned with Galaxy Unpacked, which made the perfect recipe for heavily discounted Samsung products.
