I almost always message the winning bidder of my items, thank them for their quick payment, say the item was shipped, what method I used, and provide the delivery confirmation #. I recently forgot to email a buyer. She purchased a t-shirt from me in the a.m., and I shipped that afternoon using Priority Mail. She got the item in 2 days, but sent me a message saying that I was rude not to provide her with shipping info and that although she liked the dress, she would leave me negative feedback due to my lack of communication (though she never messaged me for shipping info- I ALWAYS respond to my messages). But honestly, she received it TWO DAYS after she paid for it, and she likes the dress. Is that really a cause for a negative? Then I realized that about 95% of the time, as a buyer, I don't receive any contact from the seller regarding shipment (or at all). I'll contact them if it gets to be a week later and I have no item. Do you think I'm being unreasonable for being upset? As sellers, do you always inform the buyer of shipment? And as buyers, do you get upset if a seller doesn't immediately message you with shipping info? Sorry this was so long, and thanks for letting me rant!
