I have only been back into Lego since the beginning of this year, my 'dark ages' lasted from mid 1970's till a year or so ago, when I found the Architecture Series 'Robie House' and decided to get it. I think I have collected about 20 sets since then.
I have noticed though that new sets get released here in the USA, and I read about them here and other forums, but they don't seem to appear on the S@H site right away, they seem to be available at other retailers first. Is that usually the case? I would think they would want to have them available on the Lego site first, and then be available elsewhere. I guess its all marketing. I know enough to make sure I check prices at as many places as I can though! TRU seems to like having a couple sets at below SRP, but more of them at over SRP, got to do the research before buying, like for anything else.
