My biggest mistake so far was to send a package to the UK but without tracking to save on fees. It was costing me 70-80$ with tracking so I opted for no tracking at 50$.

Client haven't received it and since there's no Tracking I feel obligated to do the work again and send it with tracking. A lot of money will be lost but brand reputation is everything to me.

(I have my website really really soon btw 🤗)
