So apparently, they either changed the date for the ACAD sale since I looked it up or it was misprinted because I just found out I missed it! I could honestly cry. I looked it up at least a month ago and wrote it on the calendar so that I couldn't possibly miss it. I sure as hell can't afford normally-priced art, so this was my one really good chance. My only consolation is that I was way too busy last weekend anyway and would probably not have been able to go. I'm trying to shrug it off, but I'm pretty devastated. 
I was also quite disappointed.
