It used to be a 4 or even 5. But this new backorder policy is beyond terrible. I didn't even realize until I was about to send in my order that something was wrong. The total cost seemed awfully high. I looked more closely and saw that things I had ordered had suddenly been changed to ordering 3 or even 10 units when I had ordered 1. While the small print on the product pages does say out of stock and that there is a minimum order, it's not real visible and it's not ever confirmed. I could have easily accidentally ordered $100+ worth of stuff I didn't want and I could still be waiting to get it. This is a software fix. And one that shouldn't be hard for your web programmer. Once I was able to get my order to reflect what I wanted to order, everything went smoothly as usual.
