Heres the script.
Basically, just trades 1 ANNICOIN (Christmas token) for demon armor.
Code: 
function msgcontains(txt, str)
	return (string.find(txt, str) and not string.find(txt, '(%w+)' .. str) and not string.find(txt, str .. '(%w+)'))
end
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

function onCreatureSay(cid, type, msg)
	msg = string.lower(msg)

	if (msgcontains(msg, 'hi') and focus == 0) and getDistanceToCreature(cid) < 4 then
		selfSay('Hello ' .. getCreatureName(cid) .. '! say magic sword or the anni reward you want!')
		focus = cid
		talk_start = os.clock()
	elseif msgcontains(msg, 'hi') and (focus ~= cid) and getDistanceToCreature(cid) < 4 then
		selfSay('Sorry, ' .. getCreatureName(cid) .. '! I talk with you in one minute.')
	-- Demon armor
	elseif msgcontains(msg, 'demon armor') then
		selfSay('Do you want to trade one Annilator Token for demon armor?')
		talk_state = 1
		talk_start = os.clock()
	elseif talk_state == 1 and msgcontains(msg, 'yes') then
		if getPlayerItemCount(cid,6527) >= 1 then
			if doPlayerRemoveItem(cid,6527,1) then
				selfSay('There you go, No refunds.')
				doPlayerAddItem(cid,2494,1)
			end
		else
			selfSay('I\'m afraid you don\'t have an Anni-Token')
		end
	-- Sov
	elseif msgcontains(msg, 'magic sword') then
		selfSay('Do you want to trade one Annilator Token for magic sword?')
		talk_state = 1
		talk_start = os.clock()
	elseif talk_state == 1 and msgcontains(msg, 'yes') then
		if getPlayerItemCount(cid,6527) >= 1 then
			if doPlayerRemoveItem(cid,6527,1) then
				selfSay('There you go, No refunds.')
				doPlayerAddItem(cid,2400,1)
			end
		else
			selfSay('I\'m afraid you don\'t have an Anni-Token')
		end
	-- SCA
	elseif msgcontains(msg, 'stone cutter axe') then
		selfSay('Do you want to trade one Annilator Token, for stone cutter axe?')
		talk_state = 1
		talk_start = os.clock()
	elseif talk_state == 1 and msgcontains(msg, 'yes') then
		if getPlayerItemCount(cid,6527) >= 1 then
			if doPlayerRemoveItem(cid,6527,1) then
				selfSay('There you go, No refunds.')
				doPlayerAddItem(cid,2431,1)
			end
		else
			selfSay('I\'m afraid you don\'t have an Anni-Token')
		end
	end
end

Heres the error I get.
