Am I being scammed?

Hey guys,

I own a cosmetics company in Australia and have been approached by a company called Buy2Sell which is asking to purchase our products.

Usually, I ask for payment upfront via wire transfer and wait a few days before releasing any products to protect myself from scams, but wanted to know if the site is legit.

There's something off about how they portray themselves online that doesn't give me 100% confidence. They seem to have shops around Vietnam though.

The domain name of the email address I'm getting is buy2sell.vn

Any advice about this company would be great. So far I haven't found anything negative, it's just that the ads and articles look a bit weird to me. Thank you.
