[Unsolved]Problem with Developer Product?

I got the script Working; But when ever the Player who** bought the weapon dies he/she loses the weapon they bought from Dev Products**. So I want to know how can I give the Player the weapons so he/she won't lose there weapons if they die.

local plr = script.Parent.Parent.Parent.Parent.Parent
local link = game:GetService("MarketplaceService")
deb = 0


script.Parent.MouseButton1Click:connect(function()
local marketId = 21055724
link:PromptProductPurchase(plr,marketId)
link.ProcessReceipt = function(receiptInfo)
if Enum.ProductPurchaseDecision.PurchaseGranted and receiptInfo.PlayerId == plr.userId then
if deb == 0 then
deb = 1
local c = game.Lighting.DualIllumina:Clone()
	c.Parent = plr.Backpack
wait(1)
deb = 0
end
end
end
end)

Spongocardo do you mean like this because I tried this a it doesn't seem to work :L but have you got any other solutions that I could try?

local plr = script.Parent.Parent.Parent.Parent.Parent
local link = game:GetService("MarketplaceService")
deb = 0


script.Parent.MouseButton1Click:connect(function()
local marketId = 21055724
link:PromptProductPurchase(plr,marketId)
link.ProcessReceipt = function(receiptInfo)
if Enum.ProductPurchaseDecision.PurchaseGranted and receiptInfo.PlayerId == plr.userId then
if deb == 0 then
deb = 1
local c = game.Lighting.DualIllumina:Clone()
	c.Parent = plr.Backpack
local b = game.Lighting.DualIllumina:Clone()
    b.Parent = plr.StarterPack

wait(1)
deb = 0
end
end
end
end)

You can try something like this. I believe CharacterAdded is fired every time someone spawns. I did not test this script, so you may need to debug some things. Like the link to the player and his backpack. Good luck!

local link = game:GetService("MarketplaceService")
deb = 0

game.Players.PlayerAdded:connect(function(plr)
	plr.CharacterAdded:connect(function(character)
		local marketId = 21055724
		link:PromptProductPurchase(plr,marketId)
		link.ProcessReceipt = function(receiptInfo)
			if Enum.ProductPurchaseDecision.PurchaseGranted and receiptInfo.PlayerId == plr.userId then
				if deb == 0 then
					deb = 1
					local c = game.Lighting.DualIllumina:Clone()
					c.Parent = plr.Backpack
					wait(1)
					deb = 0
				end
			end
		end
	end)
end)

game.Players.LocalPlayer:Died:connect(function()
(Clone the tool and put it in the backpack here)
end)
