Hi @adlinkpen
I have never charged for any packaging materials even if an item sells for just 99p plus post at flat rate cost - the buyer has a bargain. I considered this part of a good service for my buyers, and as some items sold for a higher price than originally thought , I think it balances it out when purchasing packaging materials to post.
I recycle boxes, made up boxes from larger cardboard with strong packing tape, have had to purchase new boxes for certain items though. For fragile items I have used goat wool ( clean and washed ) which was free ( or you could use old jumpers/material or duvets as long as clean and washed) Usually cut them up and super for delicate items as an extra protection...I usually save nice boxes from gifts such as candle boxes as these can be quite strong and are super for small items; of course tissue paper, bubble wrap and packing peanuts cost more, and used those frequently, but really I feel it is part and parcel of selling. You could also perhaps salvage packing materials from anything you have bought from another seller or other items purchased...such as shoe boxes. I know some add to their post costs which now with SD isn't an option, some may choose to incorporate in their prices when listing, but as a private seller I have never felt the costs of packaging an issue as genuinely happy that someone had chosen to purchase from me.
Edit.. spelling.
