Calculators and – of late – mousepads are right there at the top of the list of most popular premium incentives. So why did it take so long for someone to come out with a calculator-mousepad? Actually, Toronto’s Aware Marketing Group introed this happening hybrid two years ago, but it just recently brought the item to life by offering the option of a four-color laminate on the mousepad. Prices range from $8 to $15 per, depending on the quantity ordered and the style (you can get a two-color image or plain black). A handy feature: The calculator pops in and out.
