Limit to 1 product per order

I need to limit an order to ONE product, but the product can be one or more of the exact same item (that is set in the actual product).

In other words, ONE “Product”/SKU per ONE “Purchase” (and quantity choice as is currently settable per product).

So a person can order one SKU with choice of quantity as set on the product.

Just can’t see where to set that.

There isn’t a built-in option to limit carts to a single product. We haven’t come across this feature request before, most stores aim to maximize sales and have customers purchase as many items as possible.

If more people think this would be useful to them, please post in this thread.

I really need this… just a thought…
would it be any easier to implement at the “Product” level?
(So if option checked, it goes straight to checkout?)

Wouldn’t you also be able to limit orders via form validation and a bit of JavaScript / jQuery?

bump… @martin just waiting and wondering about this…
(Again… I’m stuck without this)
Thanks!

Basically, the reasoning is the same logic (as the shipping / billing issue), in that product might be sourced from USA, and therefore other items sourced from other countries can’t be on the same order.

(ref Failing to allow diifferent BILLING Address)
