Advice for shipping

Hi guys.

I'm tired if trying to sell on ebay and like this modern format. I'm ready to purge a bunch of stuff.

I'm a bit nervous about how I will do the shipping. I can maybe borrow a scale but i also need to get boxes and other shipping materials. My budget is tight so I don't want to waste money on materials I won't use.

As far as I know whatnot will not let me select a custom charge for shipping. To get the buyer to pay I have to give the weight and print their label. I dont have a printer either so will have to use someone else's. I could include free shipping but then whatnot will take a larger cut.

Can I please get advice from someone else who had this problem? Or any insight. Thanks
