I just took a look at the GG website, and it looks like they announce upcoming sales at least a day in advance on their site. So right now, it shows who will be on sale tomorrow (you have to scroll down a bit on the main page). My suggestion would be taking a look at that and then setting a reminder for yourself to go to the sale when it opens the next morning. It works for me with RLL, at least.
Heather, I have had luck with RLL. I have ordered a few things that just didn't work and returned them, but I have purchased things I have kept as well--mostly tights and a few baseball tee-shirts for my boyfriend, but that's because I can be difficult to fit and am notorious about ordering things only to have to return them. I have also found RLL customer service to be very nice. I ordered a Pink Tartan suit from them once, and the skirt fit but I needed one size smaller in the jacket. I called on the off-chance that they might have a jacket in my size in their warehouse (even though the sale was over), and they didn't, but the customer service woman gave me free shipping on my next order just because it was sad that I couldn't get the jacket in my size!
