Get this Canon All-in-One Laser Printer for 65% off with free shipping! It normally retails for $199.00 and they have it on sale for $69. Laser printers are awesome for high volume printing (great for people who print insane amounts of coupons at home like me).
You can also get this Samsung Over-The-Ear Bluetooth 3.0 Headset for just $4.99 after mail-in rebate. This headset normally costs $59.99 and is on sale for $24.99. You send in for the $20 rebate from Samsung before 9/15/11 and your final cost is just $4.99! That's a savings of 92%!
