For years I've offered customers a flat rate with my small widgets, using first class with a delivery confirmation (which means I have to use a thicker envelope). Lately I have been getting customers complaining about the tracking number showing that the package is stuck in some limbo, like a "sort facility," or it says "delivery status not updated." I'm wondering if other folks who use USPS for shipping have noticed a decline in the accuracy of first class delivery confirmations? I checked back several months, and I see this with first class but not with priority (only found one priority like this).
Also, if you have used first class before and switched to priority for shipping, did you notice a change in sales? I have resisted changing to flat rate priority because not many folks who sell these little widgets use it. Most don't even use delivery confirmation.
Please, no anti-post-office rants. I don't want to hear it. I am talking business here, not politics.
