When you literally don’t want or need anything but sell on eBay and Mercari and have to give gift ideas, that are also a business expenses, then you ask for a label printer.
I got one a few months ago and I love it. I used to print on the sheets with two labels on my normal printer. Now I can print a string of ten of them at a time with ebay.
They change your world, brother. I got mine a few Christmas’s ago…I also got free labels off of a local buy nothing listing. Finally ran out a few months ago, then got another 1000 labels or something crazy for my birthday last month.
