Can you use 2 Data store in a game?

Hello, so I am learning how to save player data and I am making a Clothes Shop. Now I have to save the clothes that players bought. I can save those but when I try to save the cash, it is unable to be saved. Can someone help me with this code?

local ds = game:GetService("DataStoreService"):GetDataStore("PlayerDataStrings09")
local ds2 = game:GetService("DataStoreService"):GetDataStore("PlayerCash07")

game.Players.PlayerAdded:connect(function(player)
	local key = "user:"..player.userId
	local folder = Instance.new("Folder",player)
	folder.Name = "leaderstats"
	local cash = Instance.new("IntValue",folder)
	cash.Name = "Cash"
	cash.Value = 1000
	local folder2 = Instance.new("Folder",player)
	folder2.Name = "Clothes"
	local currentoutfit = Instance.new("StringValue",folder2)
	currentoutfit.Name = "CurrentOutfit"
	local shirt = Instance.new("StringValue",currentoutfit)
	shirt.Name = "Shirt"
	local pants = Instance.new("StringValue",currentoutfit)
	pants.Name = "Pants"
	
	player.CharacterAdded:connect(function(character)
		if shirt.Value ~= "" then
			character:WaitForChild("Shirt").ShirtTemplate = shirt.Value
			character:WaitForChild("Pants").PantsTemplate = pants.Value
		end
	end)
	local save = ds:GetAsync(key)
	if save then
		cash.Value = save[1]
		for i,v in pairs(save) do
			if game.ReplicatedStorage.Clothes:FindFirstChild(v) then
				local realClothes = game.ReplicatedStorage.Clothes:FindFirstChild(v):Clone()
				realClothes.Parent = folder2
			end
		end
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local key = "user:"..player.userId
	local cash = player.Cash
	ds:SetAsync(key,cash.Value)
end)

game.ReplicatedStorage.BuyShirt.OnServerEvent:Connect(function(player,shirt,pants,cName)
	local key = "user:"..player.userId
	player.Character:WaitForChild("Shirt").ShirtTemplate = shirt
	player.Character:WaitForChild("Pants").PantsTemplate = pants
	player:WaitForChild("Clothes").CurrentOutfit.Shirt.Value = shirt
	player:WaitForChild("Clothes").CurrentOutfit.Pants.Value = pants
	local clothes = Instance.new("BoolValue",player.Clothes)
	clothes.Name = cName
	local newShirt =Instance.new("StringValue",clothes)
	newShirt.Name = "Shirt"
	newShirt.Value = shirt
	local newPants =Instance.new("StringValue",clothes)
	newPants.Name = "Pants"
	newPants.Value = pants
	local clothes = {}
	for i,v in pairs(player.Clothes:GetChildren()) do
		if v.Name ~= "CurrentOutfit" then
			table.insert(clothes,v.Name)
			ds:SetAsync(key,clothes)			
		end
	end
end)

Yes, you can use 2 data stores in one game. Read more on the wiki. http://robloxdev.com/api-reference/class/DataStoreService http://robloxdev.com/code-sample/DataStore-Budget

Now I have 2 Data Stores. But when I buy clothes and left the game and rejoin back, my cash is still 1000. Can anyone help me with this script?

local ds = game:GetService("DataStoreService"):GetDataStore("0PlayerDataStrings09")
local ds2 = game:GetService("DataStoreService"):GetDataStore("0PlayerCash07")

game.Players.PlayerAdded:connect(function(player)
	local key = "user:"..player.userId
	local key2 = "user:"..player.userId.."cash"
	local folder = Instance.new("Folder",player)
	folder.Name = "leaderstats"
	local cash = Instance.new("IntValue",folder)
	cash.Name = "Cash"
	cash.Value = 1000
	local folder2 = Instance.new("Folder",player)
	folder2.Name = "Clothes"
	local currentoutfit = Instance.new("StringValue",folder2)
	currentoutfit.Name = "CurrentOutfit"
	local shirt = Instance.new("StringValue",currentoutfit)
	shirt.Name = "Shirt"
	local pants = Instance.new("StringValue",currentoutfit)
	pants.Name = "Pants"
	
	player.CharacterAdded:connect(function(character)
		if shirt.Value ~= "" then
			character:WaitForChild("Shirt").ShirtTemplate = shirt.Value
			character:WaitForChild("Pants").PantsTemplate = pants.Value
		end
	end)
	local save = ds:GetAsync(key)
	local save2 = ds2:GetAsync(key2)
	if save then
		for i,v in pairs(save) do
			if game.ReplicatedStorage.Clothes:FindFirstChild(v) then
				local realClothes = game.ReplicatedStorage.Clothes:FindFirstChild(v):Clone()
				realClothes.Parent = folder2
			end
		end
	end
	if save2 then
		cash.Value = save2[1]
	else
		ds:SetAsync(key2,cash.Value)
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local key2 = "user:"..player.userId.."cash"
	local cash = player.leaderstats.Cash	
	ds:SetAsync(key2,cash.Value)
	
end)

game.ReplicatedStorage.BuyShirt.OnServerEvent:Connect(function(player,shirt,pants,cName)
	local key = "user:"..player.userId
	player.Character:WaitForChild("Shirt").ShirtTemplate = shirt
	player.Character:WaitForChild("Pants").PantsTemplate = pants
	player:WaitForChild("Clothes").CurrentOutfit.Shirt.Value = shirt
	player:WaitForChild("Clothes").CurrentOutfit.Pants.Value = pants
	local clothes = Instance.new("BoolValue",player.Clothes)
	clothes.Name = cName
	local newShirt =Instance.new("StringValue",clothes)
	newShirt.Name = "Shirt"
	newShirt.Value = shirt
	local newPants =Instance.new("StringValue",clothes)
	newPants.Name = "Pants"
	newPants.Value = pants
	local clothes = {}
	for i,v in pairs(player.Clothes:GetChildren()) do
		if v.Name ~= "CurrentOutfit" then
			table.insert(clothes,v.Name)
			ds:SetAsync(key,clothes)			
		end
	end
end)
