Just re-posting this so you remember!
I am pleased to let you know that the $1 Old Navy Flip Flip sale is coming up.  Mark your calendars for June 30th.  Normally the stores open early because this is a big deal :)  I went a few years ago and still have my flip flops, they hold up really well. There is a limit of 5 per person and this is valid on the regular flip flops, not wedges or ones with designs.
