I recently purchased an item from another Etsy seller and had paid $4.95 in shipping charges. When the box arrived I noticed the postage paid was $2.30.
I am very happy with the item, and it did arrive quickly and in good condition, but I feel more than a little cheated on the postage. I know that it can be difficult to estimate the postage and sellers don't want to lose money on it - but this feels like a big difference to me. Because the product quality was good, something like this wouldn't make me leave negative feedback, but it would certainly stop me from ordering from her shop again.
I've been stewing on this for a few days, and it bugs me but I don't know what to do about it. Take a deep breath and let it go?
