Amazon is having a pretty good deal on GU Energy Lab Gels, 24 count boxes. If you have Amazon Prime, it is an even better deal. It is currently $25.59 or $1.07 per packet. Here is a link to get in on this bargain. They have many different flavors also. GU is the only brand I use, so I will be getting at least one box!
Here is a QR Code to the sale as well.
