I have this Perk Shop script:

local MarketplaceService = game:GetService("MarketplaceService")
local AddHealthID = 20433249 --ENTER 
local AddSpeedID = 20438665  --PASS
local AddGearID = 21739855   --IDS
local AddGear2ID = 21739858   --IDS
local AddGear3ID = 21739864  --HERE
local PurchaseHistory = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")
MarketplaceService.ProcessReceipt = function(receiptInfo) 
    local playerProductKey = receiptInfo.PlayerId .. ":" .. receiptInfo.PurchaseId
    if PurchaseHistory:GetAsync(playerProductKey) then
        return Enum.ProductPurchaseDecision.PurchaseGranted
    end
    for i, player in ipairs(game.Players:GetPlayers()) do
        if player.userId == receiptInfo.PlayerId then
            if receiptInfo.ProductId == AddHealthID then
				player.Character.Humanoid.MaxHealth = player.Character.Humanoid.MaxHealth + 50 --Adds 50 to their current health
				player.Character.Humanoid.Health = player.Character.Humanoid.MaxHealth
			end
			if receiptInfo.ProductId == AddSpeedID then
				player.Character.Humanoid.WalkSpeed = player.Character.Humanoid.WalkSpeed + 15 -- Adds 5 to their current Walkspeed
			end
			if receiptInfo.ProductId == AddGearID then
				game.ReplicatedStorage.DualVenomshanks:Clone().Parent = player.Backpack -- put the gear in ReplicatedStorage then put the name of the gear in the GEARNAMEHERE
				-- game.ReplicatedStorage.GEARNAMEHERE:Clone().Parent = player.StarterGear -- Add this back in if you want them to get this item till they leave the game, Like renting it
			end
			if receiptInfo.ProductId == AddGear2ID then
				game.ReplicatedStorage.GravityCoil:Clone().Parent = player.Backpack -- put the gear in ReplicatedStorage then put the name of the gear in the GEARNAMEHERE
				-- game.ReplicatedStorage.GEARNAMEHERE:Clone().Parent = player.StarterGear -- Add this back in if you want them to get this item till they leave the game, Like renting it
			end
			if receiptInfo.ProductId == AddGear3ID then
				game.ReplicatedStorage.Jetpack:Clone().Parent = player.Backpack -- put the gear in ReplicatedStorage then put the name of the gear in the GEARNAMEHERE
				-- game.ReplicatedStorage.GEARNAMEHERE:Clone().Parent = player.StarterGear -- Add this back in if you want them to get this item till they leave the game, Like renting it
			end
		end
	end
    PurchaseHistory:SetAsync(playerProductKey, true)	
    return Enum.ProductPurchaseDecision.PurchaseGranted	
end

And then this in starterpack so that the cash perk will work:

local MarketplaceService = Game:GetService("MarketplaceService")
local ds = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")
 
CASHID = 00000000 -- Put the ID of the Developer Product here. Dont forget to erase the 0's.

MarketplaceService.ProcessReceipt = function(receiptInfo)
	local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_product_" .. receiptInfo.ProductId
	local numberBought = ds:IncrementAsync(playerProductKey, 1)
	for i,v in pairs (game.Players:GetChildren()) do
		if v.userId == receiptInfo.PlayerId then
			if receiptInfo.ProductId == CASHID then
			
			
				lds = v:FindFirstChild("leaderstats")
				if lds ~= nil then
					cs = lds:FindFirstChild("Coins") --Change to your leaderstat that you want it to add to.
					if cs ~= nil then
						cs.Value = cs.Value + 1000 --Change to the amount of Coins you want to add.
					end
				end
			end
		end
	end
	return Enum.ProductPurchaseDecision.PurchaseGranted		
end


				-- Put this script in the Starter Pack when you are done editing it :)

There is one problem, the second script causes the top one not to work. Maybe because it is in starterpack. Help if you can because i dont know how to fix it....
