JW is currently selling the PNY 8GB eraser usb 2.0 memory sticks for $6 each with free delivery today only. Comes with an eraser and is waterproof. Cheapest price in Australia from what i can tell (some stores may not have stock)
In addition the Bella Vista store is having a moving sale up to 90% off selected products. However it does not mention what is actually on sale. Most likely most items won't be heavily discounted. Moving sale ends on Sunday.
Strange combo!
I guess you cannot make too many mistakes… otherwise you'll end up without a lid for your USB drive
