I can't prove anything's wrong but my gut instinct is so strongly telling me that something doesn't feel right.
I've been on Ebay for years and usually sell average clothes. It's unusual for anyone to send me questions as my wording is very clear. I have minimal communication with my buyers, if at all.
Last week I sold an original t-shirt of a 90s band for what I thought was quite a high price, as I know from searches that these things sell.
Within only a few minutes of putting the listing up, I received a message asking me if I had any more t-shirts to sell. I replied to say no. I then looked at the guy's profile and he was actually a reseller of band t-shirts, so I'm glad he didn't buy it as I hate the thought of people buying my stuff just to sell on. I know a lot of people don't mind, but personally it makes me feel very uncomfortable when people are so blatant about it. I know there aren't any rules against it but I hate the thought of people doing this with my stuff, especially when they're buying and selling on the same account so not even trying to hide it. I've done it myself a couple of times with a very occasional charity shop item, but I would never be so blatant about it or shove it in the seller's face.
A few minutes later, only ten minutes after the listing going live, someone else buys the item but it says awaiting payment. I didn't even realise this was possible as I was sure I'd set up my account to require immediate payment, but I was wrong about that.
The buyer then sends me a message asking if I have any more t-shirts for sale! I reply to say no. Buyer then pays. I look at their profile and it's only a few months old and has only been used to buy band t-shirts.
I mean there's nothing technically wrong here, but my instinct is pulling so strongly on this one. I can't even explain why.
