Everyone's favourite Science museum, Questacon, currently has 20% off everything on their online store until the end of March 2018, in addition to selective end of year discounts. There's a huge range of science-focused products - Books, Puzzles, Toys, Gadgets, Telescopes, even labcoats. Postage is a flat $10 for all orders. Some highlights:
3D Printing Pen - RRP $149, currently $71.52 + postage
Bacon Toothpaste - RRP $13, currently $7.28 + postage
Analogue LED Projection Clock - RRP $99, currently $55.44 + postage
Air Power Engine Car - RRP $58, currently $37.12 + postage
Theo Jansen's StrandBeest - RRP $69, currently $38.64
Some very cool stuff. I picked up some Light Stax (the "Advanced" box with 36 pieces) for $54.24 (incl. shipping) because the 20% coupon stacks with any discounts (currently there's up to 30% on selected construction toys). An absolute steal for something that is ~$79 everywhere else. Just disappointed I only found out 5 days before Christmas! Have fun.
Ah Questacon, highlight of year 5 camp!
