DevProducts are giving you what you've already bought?

So, this script is rather messy but I'm just looking for one bug. This is for a dev product GUI. The GUI works well but every time you buy a new dev product, you get the new gear/money and also everything you had previously bought in the session. Help would be appreciated as well as any optimisation but i'm not to bothered about having it not lag as it is one of the only scripts in the game. I also understand there is probably a way to only use the purchases dictionary in one of the scripts but again, I have little interest in optimisation.

Global Handler: (Sorry for no indents!)

mp = game:GetService("MarketplaceService")
gui = script.Parent
purchaces = {["+health"] = 36743582, ["+speed"] = 36743578, ["10k"] = 36739107, ["20k"] = 36742505, ["30k"] = 36742526, ["40k"] = 36742576, ["50k"] = 36743511, ["5k"] = 36738719, Bomb = 36743569, Jetpack = 36743595, ["Laser Gun"] = 36743566, NUKE = 36743610, Rocket = 36743561} --REPLACE NUMBERS WITH GAMEPASS ID'S

mp.ProcessReceipt = function(receiptInfo)
reward = nil
for i,v in pairs(game.Players:GetChildren()) do
if v.userId == receiptInfo.PlayerId then
if Enum.ProductPurchaseDecision.PurchaseGranted	then
local id = receiptInfo.ProductId
for i,v in pairs(purchaces) do
if v == id then
reward = i
end
end
if #reward == 3 then
local cash = string.sub(reward,1,2) .. "000"
v.leaderstats.Cash.Value = v.leaderstats.Cash.Value + tonumber(cash)	
elseif reward == "+health"	then
v.Character.Humanoid.MaxHealth = v.Character.Humanoid.MaxHealth + 10; v.Character.Humanoid.Health = v.Character.Humanoid.Health + 10
print(v.Character.Humanoid.Health)
elseif reward == "+speed" then
v.Character.Humanoid.WalkSpeed = v.Character.Humanoid.WalkSpeed + 10
elseif reward == "Bomb" then
game.ServerStorage.FuseBomb:Clone().Parent = v.Backpack
elseif reward == "Laser Gun" then
game.ServerStorage.hyper:Clone().Parent = v.Backpack
elseif reward == "Rocket" then
game.ServerStorage.RocketLauncher:Clone().Parent = v.Backpack
elseif reward == "Jetpack" then
game.ServerStorage.JetPack:Clone().Parent = v.Backpack
end
else
warn("ERROR - PURCHACE ABORTED OR FAILED")
end		
end
