Sheesh, that's dear.
Just get 5 mm Clear Toughened (Tempered). You don't need the Edgework (just wasting your money).
Toughened glass will come with a 'Rough Arris' edge as standard, which is good enough, because the edges aren't seen.
 
Trust me......I'm a Glazier.  
 
I'm a long way from you, otherwise I'd get you some cheap glass.  
$ 40 - 50 is ok price.
 
I don't want to upset you all.....but it would cost me approx $ 17 + Gst.
I would happily sell some to you guys except I'm in Hervey Bay. Qld. .....and I'm not posting any glass, for obvious reasons.
