Ok, I will repeat it: What would you do if your buyer gets their parcel two months later ...
Who, I as seller?
Apologize for the postal delay and offer to throw in a freebie with the next order. Happens all the time. Take responsibility, make the buyer feel valued, look for repeat business.
Who, I as buyer?
Chalk it up up to slow postal service, especially if the postage stamp evidences expedited dispatch, don't take it out on the seller. Been there, done that.
As as seller, one must always, repeat, always remain sovereign, "above it all", and focus on customer satisfaction. After all, as a seller, you hold way more power that the occasional shopper and, therefore, should comport yourself graciously.
Why are you so defensive anyway?
I'm not. I'm having fun and, in the process, some people are falling for it ]:)
