https://www.samsung.com/us/smartphones/galaxy-z-fold6/buy/galaxy-z-fold6-256gb-unlocked-sm-f956uakaxaa/Must use the Samsung Shop app to get this price. (For those on iPhone the Shop Samsung app doesn't have the Fold6. Use a regular browser and sign into a Samsung account and then add the Fold6 with the no trade in option - the price will be $1099.99 - and then sign in on the app on iPhone (or Mac with apple silicone) and you can checkout with the additional discounts.)
List price $1899.99
Black and White colors have $300 off = $1599.99
Select 'No Trade-in' $500 Samsung Instant Savings = $1099.99
Shop Samsung app brings the price down to $939.99 (A $50 promo code should automatically add to your cart, Samsung has a $50 off $500 in app promotion.)
The last step is to apply a referral code (new accounts only, so just make a new account, phone does not get connected to the account you use to purchase it) which will bring the price down to $890.40. There are many reddit forms dedicated to Samsung referral codes. Or make another account and refer yourself.
Price can go lower if you have a id.me verified account with education etc.
p.s. Sometimes the app doesn't accept referral codes. In that case use the iPhone method above and add the promo code in browser.
