Heipi has 13% off their travel tripod, which should bring it down to $350 or so.
Peak Design’s deals are live. 30% off their carbon fiber tripod ($420), Capture Plate in Silver ($53), 65L travel duffel. Lot of other stuff at lower discounts, like other bags, straps, etc.
But if you take your camera hiking, buy that Capture Plate now and ask questions later.
If you need storage space for your photos (and remember, 2 is one and one is none):
Costco has Seagate Expansion 14TB external HDDs for $150. Useful for a backup solution, or if you don’t care about warranty and want to shuck them for use in a NAS.
B&H has Seagate 16TB Ironwolf Pros for $200 after coupon. Bit more expensive per TB, but full five-year warranty, along with 3 years of Data Recovery. Great option if you’re looking to build or expand a NAS.
