Yes, it is very expensive - especially when you compare it to Boost or Ensure.I'm afraid I'm not seeing any offers for samples on their website. But, here's their website if that helps any. You can get coupons from them though. I found Pronourish at Safeway today. But, didn't pick up any because even with my $2 coupon it would have been about $11 for 6 bottles. So, will have to think about it.
