Let me start by saying I can confirm some of the other reviews regarding 'rip off' practices. I call it FRAUD.
I sent 2 boxes (purchased at the UPS store). The box size was printed right on the box and nothing was over stuffed. The price seem unusually high. I questioned it but was told that was the rate. I was in a rush so just paid and went to my next appointment. That night, I looked at the tracking info and sales receipt and found that both box sized were inflated by 1 inch or more. When I checked the prices for the correct size, the price difference was $5-6 per box.
I contacted UPS Fraud (fruad@ups.com) and they told me to contact the owner (why would they care, UPS is making out too). When I did try and contact the owner, he can't be found, always at a different store and no one will give me his cell number. This guy has 3 stores, Goodyear, Buckeye, and Glendale. If he rips off every package for a couple of bucks, that's pretty good money - Do the math!
Stay away and tell your friends.
