Thanks to Frugally Thrifty for passing this along,
EAS Myoplex is giving a free product coupon when you register to receive their newsletters. I did this last night and I was able to print a coupon for up to $3.89 off EAS Myoplex Bar or Shake. It looks like these coupons expire quickly after printing (*within 2 weeks**), but that is definitely enough time to get to the store and get your freebie! So, if you want your freebie, you can register here and print your coupon immediately following.
