Is there an emoticon for kicking oneself in the behind?

I had the Sigma 10-20 all set up in my Amazon cart. Today, when I went back to make the purchase, it had increased in price from $501 to $569. Grrrrr. Now, I might just as well order from Adorama or B&H.
Note to self: When you know you are going to buy something, don't wait! The price usually goes up.
I don't know what's up, but the Sigma lenses all seem to have increased by about 15%.

Ouch, that stinks. I got my 10-20 right before B&H upped the price. Amazon lagged behind for quite a while, sucks to see it has gone up everywhere now.
