Drop the price of two boxes of checks at 4checks.com from around $31.80 to $5.05 when you use code DE5278. This code also bags free shipping (though a $3.90 handling fee applies). That's $1 less than our previous mention from last month. To get this deal, put two boxes of checks in your cart and deselect the "EZShield Check Fraud Protection Program" option. Apply the code and select USPS Bulk for shipping. 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.
