Yes he's absolutely fine for instock items. Not for "fast stock/normal stock" BS. I have pre-ordered on eBay for years, with only one real problem. Leo from Goodshipped however sold many items on pre-order listing them as "shipped as soon as released" only to leave people waiting months, yes months for their orders. Whilst he sold his first batch items for silly prices. I know several other board members had similar issues with him.
He made up this ridiculous fast stock, normal stock bollox. Afterwards.
I had been ordering from him for years, but never again. There are some highly trust worthy sellers out there, who have a fair business practice and honest interaction. So it's a pity people like Leo tarnish others reputations.
I think people need to understand they have a 45 day limit to their rights with Ebay and PayPal. There' no good reason to have a transaction on there which goes longer than that without opening a claim.
