Multi-user Defect tracking software, from AxoSoft, for $5

I've been weighing up our defect tracking solution for some time now, and this offer from AxoSoft seems too good to be true.

5 user, web and windows client defect tracking software with Visual Studio 2005 integration, for $5.

It's interesting that the only reason that it's $5 and not free is that the online buying option couldn't handle $0 transactions :-)
