If you paid prior to February for shipping, you didn't pay for express shipping. All shipping was called express shipping prior to that, which is what the USPS calls it. Express shipping is now and upgrade from standard shipping, which is still USPS's Express Shipping.
Don't blame me because the USPS calls their regular shipping "express shipping."
Express is not exclusive to usps. It's a actual term. Obviously you guys know that, why else would you change it at the last minute? You could at least charge a reasonable price, these are price gouging rates. After delays, no customer support, missing specs and shipping orders out of position. You could at least do right by the customers this time... It's doesn't help offering a second shipping option anyway. It's just a last minute way to rake in more profits. And no one wants to go through usps anyway, they have the worst service of anyone.
