Perhaps worthy of its own. My recent experiences have been that if an oversize (like 9 x 12) it can incur two different rates.If flimsy, bendable it will be charged as an international letter non-standard rate(likely not the correct terminology but you get the idea.}If with a non-bendable card stiffener, it will be rated as a package at a higher rate. Considerably higher.I've had clerks debate the bendability issue.
