So, I just ordered up my usual biotin supplements through SmartPak. I did my usual google search for the "Free Shipping" coupon code that I always seem to find. In my search, I came across a $5 off coupon as well. So, I typed them both in and WAH-LAH! Free shipping AND $5 off. This $5 off is off of EACH horse's supplement. I order 2 months worth of supplements at a time, just under 2 different names for my 1 horse. Coupon gave me $5 off each month's worth of supplements.
Long story short: If you're ordering supplements through SmartPak, use these codes for savings!
FREE SHIPPING: LFS39
$5 OFF EACH HORSE'S SUPPLEMENTS: SPETS2-5
Not sure of when these codes expire. Pretty sure free shipping is only through 4/12/09.
