Ok prices are in, please do you calculations and let me know if still keen via PM along with your post code so I can firm up quote for a set/s.

Blades - $90 or $135 (less any discount for multiple sets)

Packaging - $5 - will be 2 pieces of 3mm MDF (1200 x 265mm) which will house the blades and add the required support so your blades do not bend damaged nor bent.

Freight - I am in Newcastle - so any local guys can pick up for nothing    or if you are coming to Pinfest pickup then ???
           - but for those needing it sent here are the costs. I checked out E-go as heard they are cheap but heard lots of negative things. So went through the process of cost comparing among a few companies.
So came up with Smart Send - as they have reasonable freight charge, they insure (at blade cost to you) and they have receipted delivery - so for you the customer are totally covered as well as myself as I want everyone to be happy.

Freight estimates are: (are to major cities, so once I have your accurate postcode I can finalise your final cost to you).
Sydney, Brisbane and Melbourne - $25
Adelaide - $33
Perth and Hobart - $40

as for Wonders multiple sets (4 off) to Perth - $45

so maybe share postage and purchase costs with someone else and get a set of blades for cheaper, like Wonder's purchase $40 for 1 set of freight but $11.00 per set for 4 sets = $45.

I understand if anyone is not willing if the costs have grown just PM and anyone keen PM me your postcode and once I get 12 sets with names against them I will place a order and start locking in purchase values with everyone.
