Thanks to typhoonadventure for the original EB Games sale post.
The Kiro is a great low-cost ambidextrous mouse for lefties, and a decent all-rounder for anyone who wants a competent computer rodent. It has customisable panels on both sides so you can add or remove buttons as you like. I've had one for a few years and it feels pretty good in the hand but is admittedly a lightweight device, so if you prefer a bit of heft then I'd suggest the Kova AIMO instead (currently not on sale).
The Vulcan 100 is a dream to use. I love the short-travel keys and the positive feel of the switches. It's not very noisy like some mechanical keyboards are, and I'm fairly certain you could mod it with O-rings to dampen sound even more. The lighting isn't too garish and the Swarm software gives you a fair amount of customisation. Note that it's exactly the same 'board as the Vulcan 120 and 122, just in the dark colour only and no wrist rest; unless you really want the rest or to get in white you can save a lot of money. I have seen the Vulcan 100 slightly cheaper elsewhere so you may be able to get a pricematch if you're lucky, but EB have a strict policy it must be in-stock at a bricks & mortar retailer within a 20Km radius.
