The Samsung Galaxy S26 Ultra is $390 off on Amazon US — dropping from $1,400 to $1,010 for the 256GB model, as part of the final day of Prime Big Deal Days. The discount applies only to the base storage variant. The 512GB model falls from $1,600 to $1,120. Both prices are for the unlocked version sold directly by Amazon in the US. A Prime membership is required, though the free trial suffices. The deal ends today, October 7, 2026, at midnight ET, per Amazon’s event schedule. No Indian pricing or availability is mentioned in the reporting. Only the US offer is confirmed. This is not a permanent price cut. It’s a flash sale timed to coincide with Prime Big Deal Days, and no post-sale price has been announced. The S26 Ultra launched at $1,300 for 256GB, same as the S25 Ultra. But Samsung raised it to $1,400 after launch due to rising component costs. So this deal brings the phone back below its original MSRP. Key specs remain unchanged: Snapdragon 8 Elite Gen 5 chip, 6.9-inch display with S Pen support and Privacy Display mode, 60W wired charging (0–100% in 43 minutes), and a camera system that includes a 200MP main sensor. GSMArena notes the Z Fold8 Ultra shares the 200MP main, 10MP 3x telephoto, and 50MP ultra-wide, but lacks the 50MP 5x periscope lens found on the S26 Ultra. The foldable also uses slower 45W charging and takes 60 minutes to fully charge. The S26 Ultra competes directly with the iPhone 18 Pro Max as the top-tier non-folding flagship in the US market, according to GSMArena’s comparison. It also outpaces last year’s S25 Ultra in charging speed and adds new display features. But not in base price stability. What happens next? Amazon’s deal expires tonight. Samsung hasn’t signaled any broader regional rollout or follow-up promotion. No Indian launch details, pricing, or availability appear in the source material, so readers in India should not expect parallel offers unless separately announced.
