STYLETHREAD -- LET'S TALK SHOP!

So I called and placed my order for the holly pitchers in gold and they are on backorder until the third week of may.  I went ahead and did the transaction because I was able to use the 20% off code.  I could have ordered them through zappos but I would have paid $70 instead of $60 which includes the discount and shipping from aerosoles.  Am I dumb to wait until may just to save $10?!?  I am so cheap! 

Another question, does anyone know if the 20% off code would be applicable in an Aerosole's store?
