Found a good deal but want to make sure it's not too good to be true if you know what I mean. Anyone buy from these guys?

I've bought from them a few times with no issues. 

+1 to above.

 I have purchased tires from them with no issues, low price and fast delivery. On another purchase I found that I needed to buy another part to complete installation and it was not noted in the web site, so just make sure that you have touched all the bases and know exactly what you need! The help guy was not particularly helpful, either.
