We did the surepost because it was suppose to be cheap and also quick according to the ups rep, im going to add the option for USPS priority as an option as some of the surepost packages were delivered pretty quick, but some not so much. I was leaving the surepost for the free shipping specials as we have a deal with ups which lets us ship cheap (know why now) and ill leave the option for USPS for those who dont want to wait.
Great. Few have had issues with it and many will gripe at the cost but as a option it should be fine. I print my own USPS Priority Mail postage and its only $5.25 each. Tracking is included.
