Scheduled 9 valuable collector's item auction's to end late Sunday night/early Monday morning because some eBay research indicates that it is the period of peak usage. I told my fist several buyers that I was on my way to the airport's 24 hour post office and could ship "tonight" if they paid "tonight." My brother was driving. All but one paid.
I still needed a few packaging supplies and was disappointed to find that they were closed when I got there half-past Midnight. It seems that they are closed exactly 8 hours a week, Sunday night into Monday morning. Gah! I started preparing packages to ship from the APU when it suddenly started bugging out and rebooting and claiming to be out of service. Eventually it came back online, but it went out of service again three times in a row right at the step where it prints postage. We really had to scrape to get decent packages for the remaining items, including tearing apart other packages that were not promised the same day (the two auctions which ended after we got there) and using every napkin and paper towel we had access to.
We finally tried another package and the APU worked fine, but we had to spend ages re-writing addresses since their label would cover ours up. The small flat-rate boxes are big enough for the large labels but it doesn't ask because it knows they will fit, but the label has no space for a return address and it covers all the white space leaving no room to add one! We tried the first package again and it suddenly allowed us to ship it. Strange.
We didn't get out of there until some time after 3AM and we would have been better off shipping from the local APU (close enough to source packing materials from home). From there we could've shipped all of it and been in bed two hours earlier, though they would not have been on the way to their destination as early as they were.
