2 things drive me away from a vendor faster than anything. 1. If they make it hard for me to give them money. Require a PO signed and faxed over approving the...NOPE. I will find a new solution.
Just take a CC and you are off and running!
Tried to buy a product direct from VMWare once after they bought Shavlik. So I contacted them, and tried to give them money. It took a week, and 3 faxes... yes fax after 2010. I had to write my CC number on paper and fax it to them then wait for them to email me my software. I haven't spent a dollar with them since.
