I ordered an m0 stepping P4 2.4c processor from them and had some trouble with their cart and it didn't send my credit card data into them. After 3 days of no response, I went to their website and fired off a query on my order to them. Within 2 hours I had a nice reply from Larry with Azzo telling me that for some reason my cc info wasn't with the order and he would gladly take the info and process my order. I emailed back the info needed and he promptly shipped my processor out the same day. This is the third time I've dealt with Azzo and all 3 times have been a good experience. I was really impressed with the prompt response to my query on my order and Larry worked with me to expedite my order, since I was going to work for 2 weeks in a remote location the next day. Their prices aren't the lowest, but they are a good place to go if you are looking for a particular stepping for a cpu and they don't rip you off on shipping charges either.
I would definitely buy from Azzo again.
