How to remove old characters from addon memory?

Yeah I don’t have a way to remove characters from the shopping list right now… I can put it on a list of things to add.

For now yeah, you could go into:

C:\Program Files (x86)\World of Warcraft\_retail_\WTF\Account\[your account name]\SavedVariables\AskMrRobot.lua

Open it with any text editor program, and search for the string ["Shopping2"] (exactly like that with the brackets and quotes included). Under that you should see several sections like:

["Player-Server"] = {
    ["setups"] = {
        ["Frost"] = { 
            ... stuff ...
        },
        ... more stuff ...
        ["Blood Raid"] = {
        },
        ["Unholy M+"] = {
        },
    },
},

You can delete that whole section for a player you don’t want to see anymore. Make sure to do this while WoW is completely closed, then start up the game again.
