I don't think it is that odd. He probably didn't realize that you were the same seller from the first batch when he purchased the second batch. He is probably a reseller. I doubt you have anything to worry about.Very weird!
Yes you are correct, it is a shipito address.
Should I not have messaged the buyer? [emoji15] The item he bought are teeth whitening kits. He said he buys hundreds every week so it's safe to say I think he is a reseller which I am fine with but he said he doesn't know how many he purchased from me which is a bit odd...
Too bad Watchcount doesn't work anymore. You could check his history to see if it is true. Have you checked his feedback? Does it support his claim that he buys hundreds a week? Maybe they aren't available in his country.
