We have had a few issues with this store, but after this last situation, we will never use them again. We were shipping a very small package overnight from Phoenix to Austin. The quoted rate for UPS was higher than the 1-day USPS, so we selected USPS. They charged us $55.95. The package was not received for two days and after looking up the rates with the USPS we found that they overcharged us $22.50. The USPS charge for that box, at that weight, for overnight was only $33.45, not $55.95. When we called about the money back guarantee offered on the package for on-time delivery, they refused to honor it. Their customer service is horrible and overcharging for USPS shipping is incredibly unethical. Not sure how they stay in business.
