Assure Guard gold - best way to buy

For those on the assure guard gold . . . where have you found the best deals to purchase this supplement? Local feed store carries it and charges $239 for the 16lb tub. A few of my local vets have online pharmacies and I get monthly discount codes for $25- $35 off plus free shipping but with NC tax it’s still pricey.
Anyone have other ordering suggestions?

Did you ever get an answer to this? I’ve just started feeding the supplement and am also looking for some saving tips! I am also in NC but I’m 3 hours away from the closest dealer and the $15 in shipping stinks to pay!

2 of my vets have an online pharmacy that I’m on the mailing list for. The shipping is free and they run promotions a few times a year with 10-20% off.
