So of the hundreds of ESE shipments I've sent out, I got my first 2 back requiring additional postage. See the scans. Little background, I typically send cards in a toploader with team bag wrap in a half sheet of paper for 1oz(64 cents), while anything thicker, I usually go 2oz(88 cents) or if it's a jersey card that isn't too thick I go 3 oz(1.12).
In these cases it was 64 & 88 cents. The actually problem wasn't clearly given, but I just reprinted 2 labels for $1.12 each. I'm treating this as a one off situation and will continue the status quo, but if it continues, I might have to send everything at $1.12, which I don't want to do. I'm fairly certain that I meet all the specs for ESE shipments with the rigidity being the only possible subjective violation. I saw in a different thread that people use cardsavers instead of toploaders and I'm planning to try that as well. Anyone else deal with this situation and any tips to reduce these? I did notice that there were a single ballpoint pen mark on the bottom left of both envelopes and wasn't sure if that meant anything.
***update*** I see now that these are marked for non-machining and that is what the surcharge is for. Which leads me to another question: If it is non-machinable, does the envelope still get a scan?
