Any of you dudes with Amex should sign up for Shoprunner asap. Free 2 day shipping is the shit and it applies to anything you order from Ralph. Really cuts down on the bill.
Regarding the question of switching out of RRL, I've started to curtail my purchases. I feel like the prices are getting a little too high for a lot of the items that aren't limited editions. I've already built a pretty solid RRL wardrobe so I think now I'm going to just save my cash and shoot for early retirement.
