Charge for postage labels.

[handstamped-not-printed]

Yesterday I was checking through my sales report, and spotted something that I didn't understand. There was a charge for postage labels of £61. I only started printing labels through ebay/Royal Mail last month as had always taken my orders to the post office previously, and besides, I pay for the labels immediately from my bank account so couldn't work out what this charge was for. I contacted ebay, they didn't know either! After an 'investigation' I had a call back last night saying the charge shouldn't be there (too right!) and they would refund the full amount.

Has any other business seller come across this?

Just makes me question what other things I have been charged for but not spotted!
