One thing you can never have too many of are USB keys. At some point or another, you're going to need them and, if you're looking for some affordable ones with high capacity, Canada Computers has a few on sale this weekend. As part of their Top Weekend Deals, they have the following promotions you should check out:

• Refurbished Corsair Flash Voyager 32GB USB 3.0 Flash Drive - $14.99
• Refurbished Corsair Flash Voyager 8GB USB 2.0 Flash Drive - $3.99
• Microsoft Wireless Mobile Mouse 3500 with BlueTrack Technology (White) - $9.99

The USB drives are pretty good value if you don't mind buying refurbished. The 32GB model is USB 3.0 compatible as well which means faster read/write times overall. The Microsoft Mobile Mouse is also a pretty good deal if you travel with a laptop and don't like using the trackpad. It's light, compact and a good pick up at $10.

The deals are live now but expire on August 19.

Some items have already sold out online so, if you're interested, you'll need to head to your nearest Canada Computers location.
