Drop the price of two boxes of checks at 4checks.com from around $31.80 to $5.05 via code DB4335 when you pay with a new account. Plus, this code also makes USPS Bulk for shipping shipping free (a $3.90 handling fee applies, but be sure to select this option from the drop down menu at checkout). That matches our mention from last month as the best check deal we've seen. Put two boxes of checks in your cart, and after you enter your check information, add the code and deselect the "EZShield Check Fraud Protection Program" option, which adds $4.90. Duplicate checks are available for $1 more. Sales tax is not charged in most states.
