We always use Ebay labels for our shipping along with the tracking, always try to go Priority. Buyer bought item Sunday night, item was pre-packaged, dropped off at post office Monday morning, if you had deliver directly to clerk they give us a receipt. But a lot of times my husband not wanting to deal with them just sticks it in the box. I on the other hand get it so I have one more thing of proof if I get a loon buyer. We have it set up clearly in our policy will ship out in 1-3 days after payment, well he paid right away, we had to pass post office on way down hill so we dropped it off Mon. morn. Not even 48 hrs and hes freaking on me, threatening me, accuses me of falsifing the tracking number. I informed him I did not hack into the USPS system just to alter his tracking number. So Im checking everything, checked tracking and there was an ACK, went to post office, btw shipping was estimated 5-6 days but he was going nuts, turned out they shipped but sent it back to themselves. They apologized, said it was their fault and would ship it right away back out. We also found out that in lower populated areas like where we were living the post office is now holding its packages for a couple of days till they get a larger number of packages worth sending to the distribution center because cost of gas. I'm thinking great, this guy is going to totally flip out, he wanted a refund, he was going to tattle to Ebay, bla bla bla. When we informed him of what happened and that we technically had 5-6 days shipping window, it was as if we were talking to a whole different person. Suddenly nice and polite..... somebody took their meds, I thought for sure this was going to end in an epic battle with Ebay. But he did a 180 on me and became a very nice person, maybe he just had a bad day, dunno.
