$3.77

I went to the used bookstore today and bought a copy of Alice in Wonderland by Lewis Carroll.  I was looking for a full length edition for Ivy and found a rather beat up hard bound copy. I have a credit at the used bookstore from trading books for a percentage discount on future purchases. With the discount the total for the book was $3.77.
My next errand was to the pharmacy.  I picked up a prescription and then saw there was a small basket of items on the counter for 75% off.  I saw a nice bottle of sensitive skin body wash that I thought Dave would like so I added that to my purchase. The total was $3.77. " That's interesting", I thought to myself.
I then stopped at the deli counter and asked for a small container of tropical chicken salad, thinking it would go well with some of those potato chips I bought yesterday.  The total, I'm not making this up, $3.77.
Three times seems like one time past a coincidence and so I am not sure how to respond.  Should I  freak out?  Should I buy a lottery ticket with those particular numbers?  Should I notify my family, grab my 72 hour survival kit and head for the hills?  Maybe I should stay home, lock the doors, pull the blinds, and blog about it.
