Drop the price of two boxes of checks at 4checks.com from around $31.80 to $5.05 via code DB4335. Plus, this code also makes shipping free (though a $3.90 handling fee applies). 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. At checkout, select USPS Bulk for shipping (it's the fourth option from the top). Duplicate checks are available for $1 more. It's supposed to be for new customers only, but I've ordered from them before and was able to use it. Sales tax is not charged in most states.
