If you are a member of Vocalpoint, head on over here and enter your zip code and then login to request a $2.00 off coupon! The coupons will be mailed to the mailing address associated with your Vocalpoint account.
I believe that these are priced right around $3.98 at Walmart, so only $1.98 after this coupon arrives in the mail.
Waiting is the worst part! :)
