I will never shop with zipzoomfly.
They had a 10 dollar off deal on an antec sonata that I was interested in when I was a mere noober looking for parts, Dec. 31 2004. I had read a lot of reviews (Damn tech reviews, they are as inconsistent between each other as can be!!!), and thought it a good deal. This was the last night of their deal. When I tried to purchase with my credit card, it wouldn't process. It was new years and sometimes my card doesn't process at odd times, but not from lack of funds. Well that was a Friday night, so I couldn't call zipzoomfly to find out what was wrong and what I could do, and I half expected it to be a problem on their side. Checked their site out and found that they weren't open again until Monday. On Monday I called and try to get it resolved. I had proof that I tried to order from them the Friday before, but the sales person said their prices change from day to day, and if you don't get your card processed on the day of the sale, you don't get the deal.
If only they had maintained that one 10 dollar deal, they would have gotten more of my money in the future. I explicitly told them that this case was one part of a 1050 dollar deal, and that could be proved by the shopping cart which I had filled that previous Friday with all the stuff ready to go.
Needless to say they won't see one red cent from me ever in my life, and I make sure to spread the word to whomever I can. I expect some reasonable flexible in any company that I deal with, not arrogant tactics.
I ended up going with mwave, and had no problem geting them to change certain parts of my order or answer questions, and on top of that they had a $10 off promotion. I took it as a sign. My total price there including shipping still came under zzf's price.
Good luck with that company, I am convinced they are soulless.
