For my whole life, I can't think of very many things I've ever bought when they couldn't be returned.
I( don't even bother looking at websites on which I know the return policies don't allow returns and I won't be doing thst here either.
That said, I'm not buying anything right now anyway. Some people use EZPay so they can buy more, but I use it to put a brake on my buying. When I have a whole list of accounts due, I stop as much buying as I can until they're paid. I could pay them today, but I won't. They're a good reminder I have enough for a few months.
