I've done the research several times when I've seen people making specific claims with specific prices, and each time I found it to be false. The cheapest USPS shipping for your dimensions and weight is $2.05 currently with parcel lightweight and sorting. Now what product is that size that you're comparing to? Note that the thickness here is important, as anything less than 3/4 inches thick can generally be sent in a flat envelope for considerably cheaper.
