Thanks for this, I asked about this on the weekly chat last week and they said multiple labels per sheet was a good idea, but I'm not holding my breath so I may have to invest in some A5 labels when I run out. I've been using these for years for A4 / 4 per sheet like you get from Click and Drop and have a fair number to get through.

I do hope they introduce an easier way to print multiple labels - it's not just the paper, it's the convoluted process with multiple clicks required for each label at the moment, it would be much more straightforward to just have one button to print labels for all orders.
