I must be borderline dyslexic; read it as "last ordeal".
Or, indeed, "LA St 'ho'.. ur deal"...
The issue I have with this name is in the words
'last' and 'hour'. Onehourdeals.com is an ok name,
if you can make the selling of something within 1
hour a viable proposition. Your name, however, via
the word 'last', implies that there is an element of
the site that is also about 'normal' everyday deals,
i.e. not just low 1 hr bargains.
So, in my view, 'last hour deals' is good as a site
feature, but not the whole site premise. As for
lastminute.com, I think they made it work because
'last minute' is a popular expression, and although
their name refers to 'minute' it is actually not as
time-restrictive as your name.
Good luck with it. Value, I think, is probably high $xx
to low $xxx.
