function mindcontrol.onSay(player, words, param)

    if param == '' then
        player:sendTextMessage(MESSAGE_STATUS_CONSOLE_BLUE, 'None')
        return true
    elseif param == 'test1' then 
        player:sendTextMessage(MESSAGE_STATUS_CONSOLE_BLUE, 'test')
        player:addItem(12661,1)
        player:removeItem(2173,1)
        return true
    elseif param == 'test2' then 
        player:sendTextMessage(MESSAGE_STATUS_CONSOLE_BLUE, 'test')
        player:addItem(12662,1)
        player:removeItem(2173,1)
        return true
    end

Try this. Just add the items to the table.

local items = {
    ['demon armor'] = {itemid = 2494, count = 1, payment = "money", payment_id = 0, price = 300000},
    ['mastermind shield'] = {itemid = 2514, count = 1, payment = "item", payment_id = 2520, price = 2}
}

local items_list = {}

for index, value in pairs(items) do
    table.insert(items_list, 'x' .. value.count .. ' ' .. index .. ' : Price ' .. value.price .. ' ' .. (value.payment == "money" and "gps" or ItemType(value.payment_id):getName()))
end

local str = ''

for index, value in ipairs(items_list) do
    str = str .. value .. ((#items_list > 1 and index < #items_list) and '\n' or '')
end

local talkaction = TalkAction('!shop')

function talkaction.onSay(player, words, param)
    if param == '' or param == 'list' then
        player:popupFYI("To buy an item, type the command !shop, followed by the item's name.\n\nItems list:\n\n" .. str)
        return false
    end

    local value = items[param:lower()]
    if not value then
        player:sendTextMessage(MESSAGE_STATUS_SMALL, "This item does not exist in the shop list.")
        return false
    end

    if value.payment == "money" then
        if player:getMoney() < value.price then
            player:sendTextMessage(MESSAGE_STATUS_SMALL, "You need " .. value.price .. " gps to buy this item.")
            return false
        end
        player:removeMoney(value.price)
    elseif value.payment == "item" then
        if player:getItemCount(value.payment_id) < value.price then
            player:sendTextMessage(MESSAGE_STATUS_SMALL, "You need " .. value.price .. " " .. ItemType(value.payment_id):getName() .. " to buy this item.")
            return false
        end
        player:removeItem(value.payment_id, value.price)
    end

    player:addItem(value.itemid, value.count)
    player:getPosition():sendMagicEffect(CONST_ME_MAGIC_GREEN)
    player:sendTextMessage(MESSAGE_STATUS_CONSOLE_BLUE, "You have bought a " .. ItemType(value.itemid):getName() .. ".")
    return false
