I have 2 merch amazon account, but I don't use it. I want to buy it for anyone who sell T-shirt on amazon.
Please be more specify. I am not getting what you actually want to say..
If you already have 2 merch amazon account then what you want to buy for T-shirt sellers?
Edit: I've searched about Merch by Amazon. I think you are selling your accounts to T-shirt seller not buying anything.
