i have to disagree with most people on here,
just because you said youd ship it the next day is not an initial essential part of the contract, he has purchased the item and that is the significant part to the deal.
That guy sounds like scum, that shouldnt be on these forums and shouldnt deal with anyone like that.
Whats a 1 day delay anyway? TDs can take weeks, do we email TDs calling them gay? Your unable to post it the next day and told him that..
in my opinion is the BUYER that should get over it and wait the extra day or so.
