I went to buy some specific keyboard switches last night. Ended up using one of the myriad small random vendors that the industry is full of, clearly on a Shopify cart. The checkout process had a tip button. For physical goods that will arrive in my mailbox in several weeks. Skippable and 1 to 3 percent, but still, this completely undemines any model of how a purchase transaction works to me.
