Simple story: If it looks to good to be real, it probably isn't.
I saw a great deal on NoMoreRack.com for Android Tablets for $69 each. What a steal! I purchased 4 of them for $284 including shipping on 12/05/12 and used my Paypal account. They processed my payment and the order the same day, and sent me a UPS tracking number the next day 12/06/12.
I looked back on their site 4 days later on 12/10/12 and although the order was marked "completed" with the tracking number, UPS had no record of the package. I called nomorerack customer service and was told there was a slight delay and to call back in two days if there was no change. Red Flag #1.
The next day, 12/11/12, I decided to use their Live Online customer service. But it isn't really a live person, it reverts to an email system. I got an immediate message back to wait 24-48 hours for a reply. Red Flag #2.
I called back on 12/12/12 because according to UPS, they still have not been given my shipment. NoMoreRack customer service told me it wouldn't be shipped for another 2-3 weeks due to the strike at the Port of Long Beach. Red Flag #3.
After that I contacted them twice later that day and wanted a refund. No shipment...I want out and I want my money back. Long story short...I heard two more excuses and a refusal to refund. I contacted Paypal and requested a refund through them.
Since then I have seen many instances online of similar issues happening with this company. They will take your money, print a shipping label so it looks like you are going to get your purchase, but they won't actually ship it until you complain and threaten them.
