Let's see how good you are at a Staples store to pull this off (extremely YMMV).
M185 Mouse at Staples is $19.99.
M185 Mouse at Office Max/Depot is $9.99
Price match at 110% is $8.99*.
Now the tricky part. There is a $7 off coupon at Staples so: $8.99 - $7.00 = $1.99
In-Store/Online/Phone Coupon Code: 49654
* Price overrides/matches do not affect status of regular priced items.
Most of us know the Staples guidelines, so let's see how good you really are and post your receipt .
