So basically only buy items on Prime Day or Black Friday and you're set.
Google screwed up last year and had absurd Trade-in offers to buy a Pixel 7 Pro (400$ off on years old Galaxy FE S20 for example.) +$150 off brought the phone down to $450 off contract and unlocked.
Will continue to wait for deals like that in the future.
One of the many tempting Prime Day discounts brings the US version of the Samsung Galaxy S23 Ultra with 512 GB in Phantom Black, Green or Cream finish down by 29%, so those interested can get them for US$979.99 instead of US$1,379.99. The Galaxy S23 and S23+ are also more than 25% off for the time being.
