OS is Linux Mint 19.1 Cinnamon (Tessa). Browser is Firefox 73.0.1, private window mode, with Privacy Badger to block some cookies. (I really don't trust a Google add-on to stop Google tracking, other opt-outs are often designed to be difficult to navigate, and Privacy Badger is easy to customize in order to allow cookies other blockers would block, when necessary.)

Fresh and Flavorful has had the exact same items at the exact same prices since I came back to the site about a week ago. These are Black Sesame Seeds (7,863 sP), Daikon (8,145 sP), and Water Chestnuts (10,343 sP). Because I use private window mode, my cache is always cleared when I close the window, but I have also tried manually clearing the cache. I successfully purchased Daikon at 8,145 sP, and the item behaved normally. Please let me know if you need any further information.
