A little off topic - I have a very newbie - actually signed up the day before he bought - OK - this remains ??

All my listings are 5 business days for posting - given the current conditions.

2 Days after he purchased - received an email - post urgent - provide tracking.

Having posted it with tracking 3 days after purchase - I explained to him - all sellers have a handling time - watch for it. etc.

He emailed back ' Sit ' - Kindest Regards *****

So I did. lol

Any idea what ' Sit ' means. ??
