A listing with the words 'Half Tab' or 'Part Tab' are quite common and honestly, any buyer spending that kind of money should know what he is buying, whether he or she collects Israel stamps or not.
But having said that, the price appears to be OK although I have no idea of current Scott value [My 2002 catalogue lists a MNH copy with no Tab at $225 which is about the % I stated of MNH with Full Tab.
We live and learn with this kind of item and deal and I don't think you would be justified in reorting him/her for a fraudulent listing.
Do you have a link to the ended listing ?
I have just checked a few listings both here and elsewhere and like all philatelic items, there is a bit of a price range. This particular stamp appears to be cheaper when purchased locally than from
ebay or dealer in the USA [for example].
The bottom line is it is a nice stamp and if you are happy with it then that is all that matters. I would not turn my nose up at it !

I no longer collect postage stamps but when I did, and Israel was one of my passions, I never owned this #9 !

I did handle one or two used copies but that was as close as I came.
