I had an experienced ebayer purchase something today for a discounted 'best offer' price.  They paid, then emailed: 'send by overnight post, I need this by the weekend'. 

The listing only offers standard post,and a two day handling time.  And they made no mention of it before purchasing. 

Although I have emailed and explained I can't guarantee overnight post and it would cost extra for express they haven't emailed back.  The item is not one that will fit in an express satchel or I'd wear the extra cost, even though it probably wouldn't arrive overnight anyway (coming from regional Qld, going to the bottom of NSW). 

I expect I'll get unfair feedback over it.

I justed wanted to whinge about it.  End of rant.
