im trying to find out if theres a plugin in for player vending it will only allow me to sell 1 black rasp and etc im trying to see if there a plugin that over rides that

Can't be done. The vanilla UI that players are given to administrate deployable vending machines cannot be adjusted by plugins. Only alternative would be for a plugin to create a new UI to basically replace it, but some of the interactions would be subtly different, like the item search, and how the player opens the menu.

roger ok boss no worried i guess ppl have to suck it at selling one black raspberry at a time lol
